I start one thing, and several unfinished things later I’m standing there with a spatula looking for my keys in the fridge and giggling…that’s when I know it’s time to go check! 
There are, of course, variations…
I get light headed and my thinking gets fuzzy. Not a great place to be for an IT professional.
Answers for my 5 year old son, Reed, Type 1
He gets pale, quiet and cuddly (wants to be held).
I don’t behave differently… though I’ve never actually gone THAT low. usually the way I tell is when I’m trying to get the blood on the test strip and it just WON’T GO ON because my hands are shaking. kinda scary at that point…
A pretty good sign when I catch it is worrying about a lot of things at once and being confusing at how screwed up things are. It’s good when it will dawn on me or someone reminds me that my blood sugar might be low. The CGMS makes it so nice to not have to depend on human recognition of the problem: my meter just alarms me.
Over the years, there have a lot of odd situations with lows.
Khurt, I can strongly identify with fuzzy thinking not being a great place for a IT pro.
I get hyper if it’s a low that kinda sneaks up on me. I talk in fast clipped sentences and am prone to dropping or slamming things.
If I feel it coming, I get this really weird sensation that I can’t describe - it’s like my body is empty or something - very hollow feeling and it makes my arms and legs feel heavy. I don’t get paniced or fight too much - I want whoever is around me to feed me or give me jucie!
. . . like an a*hole. I get crabby, snap at people and generally say mean things. When I start arguing with my wife and grumble at her under my breath I know it’s time to check.
Physically I feel weak, shaky and hungry.

Haha… I think I am the only person to get really nice. I get extremely nice and quiet. Its weird though when I’m around 60-80 thats when I feel really shaky and tired. When I’m 50 and below I barely notice it. I guess I just daze off into my own little fuzzy world.
hehe I can identify with each and every answer here!
I get the busy thing - Can’t stop cleaning, feel bouncy and energetic. But sometimes I get all sluggish, I feel high - even to the point of needing to gulp a lot of water and having the furry mouth feeling, and it’s those lows that tend to make me feel grumpy. No one can do anything right, no one can say anything nice, and everything is going wrong (note it’s not ME that’s getting things wrong, it’s everyone around me!! I hate that and always feel so bad afterwards).
There’s so much variation in how my lows affect me - one day I’m all happy and enjoying the feeling, the next I’m the biggest ■■■■■ you’ve ever come across. I wonder what makes them so different?
The best feeling for me is when I’m sitting pretty at 4.5 or around there (around 80mg/dl). Of course, I feel so good that I start cleaning up or just dancing around… and eventually I drop much lower. I wish I could stay at that level all day every day! My house would be so tidy lol
My reaction varies and usually starts around in the 80’s or 90’s (if it is dropping at a decent rate). Hypos almost always have an accompanying headache and strained pressured feeling behind my eyes (this happens also with hyperglycemia). Hypo Only Reactions: I also get dark swiggle looking lines dancing across my line of sight. Sometimes there is stomach pain with it, numbing around the face or in a limb. Usually I have major trouble talking (lisp and a dyslexic kind of word swapping when speaking) and thinking. Sometimes I am shaky or hyper or very drowsy and removed. I can be very indifferent or very “different” :). I feel cold, get clumsy and drop everything. Usually it seems like parts of my mind just aren’t functional. I can’t remember simple words or events, and typically have trouble understanding what people are saying. Sometimes I get a sharp shooting pain around my eyes when I am really low. When I am really low (usually the 30s, but this happened the other night when I was in the 40s) I go completely numb. I can’t stand, can’t walk, can’t talk (scary) and, despite the fact that everything is completely numb it is still painful. It’s hard to explain. Sometimes it’s a couple of those, on rare occasions (blahh) it is the whole shabang.
Thanks for asking about the lows Sarah. I just started TuDiabetes not longs ago and had only one T1 diabetic friend who went blind, had renal failure and died of a heart attack at the age of 28 a few years back. So I have been scared stiff. When ever you see diabetics interview (DLife) and they show lows those people seem so… well… cohertant. My doctors said that most people really don’t feel their lows that much especially after time has passed after diagnosis. I was starting to feel like a freak. I know that was VERY long winded, but Thank You! I feel bad that others feel bad, but at least we aren’t alone.
That’s how I get, too. I’ll know I’m low, but I just have to finish what I’m doing before going to get the sugar. I can’t drink juice until I finish washing the dishes or something, lol.
I’m glad I don’t get angry of aggressive like some folks. Usually no one could tell anything’s wrong and I remain pretty level headed and normal looking. I often get this weird cold sensation in the center of my forehead, even though there’s no sweat. Sometimes, though, there’s the shakinesss with sweat. I frequently seem to get more focused on what I’m doing when I’m low, though, like trying to finish what I’m working on before getting sugar to eat/drink. This drives my husband crazy. He’s the one that gets panicky when I say, “Uh-oh. I think I’m low.” He insists I sit down immediately and rest for 15 minutes and I always resist, lol. I argue, not because of any mental changes due to the low, but because I know I’m not going to keel over when I’m at 49! I’ve never passed out from a low.
Back when I was on Lantus I seemed to get really erratic absorption (like the whole shot would somehow get into my bloodstream within 6 hours) and I’d go very low. One morning I woke up in bed soaked with ice cold sweat and felt almost paralyzed. My mind seemed very clear, though. I felt like all the heat from the core of my body was seeping away, like I was being put into cold storage. It was this strange iciness deep inside that I can’t explain. I had the thought, “This must be what it feels like to die, when life is drifting out of your body. Interesting.” And I continued to just lie there for a few minutes pondering the sensations. I finally decided I should test my bg and sat up without a problem, feeling a little dazed, but not too bad. My meter said… 11! Yes, eleven! I thought, “No way! How can I still be conscious, then?!” I retested and it said 11 again. I got up out of bed, walked to the kitchen and stood there drinking a whole liter bottle of Pepsi. I went back and sat on my bed, still not feeling that bad. About 30 minutes after the entire liter of pop I had only risen to 40. Wow, had I been low!!!
Yeah, me too. It’s like suddenly someone pulled the plug and my muscles are draining of energy. It will feel like no matter how hard I try it would be impossible to lift the smallest weight or to keep my legs moving. The only time I experience lows in this way is while exercising.
For me, it’s like a really acute case of stomach flu, without the excrement. My abdomen cramps, and I get tingly all over, starting from my core and working out.
Interesting about the stomach and eye pain thing. Sometimes, when I’m particularly low, I get this weird pain that’s nearly identical to cramps I get from my period. It’s like low abdomen area. I asked my doc about it once, but he said that was the weirdest thing he’d ever heard. I wonder what can cause pain…? Glad I’m not the only one with something that weird =;-)
Ah, good, another strange case of abdomen cramps. Alice (a couple msgs above) mentioned stomach pain and it reminded me of my period-like cramps in the lower abdomen I get occasionally with lows under 40. Maybe it’s the muscles of the digestive system reacting to the loss of desperately needed energy? I can’t think of anything else that would cause it. Nerves, perhaps, but for me it feels distinctly like cramping pains.
Can I relate to everybody else doing something wrong NOT ME!!!
Panic… my anxiety levels got through the roof. I run around trying to do stuff then when i realise I’m going low i feel like crying… not always that bad but thats the general process! 
I feel panicky and I hate it! It’s strange though, it seems that my feelings change every 10 years or so. I used to turn into a crazy person and start screaming at everything. Before that I’d just sit down and want to sleep. Now it’s just this sense of panic like I’m dying and it’s the worst feeling ever, I’ll take what I delt with before than these feelings.
