Katie,
What an adorable baby!!!
For highs, I usually get the “cotton mouth” and have to go to the bathroom a lot.
For lows, I get verrrry hungry, lose concentration, and if I’m really low, feel a numbness or tingling on my mouth/tongue.
Both make me very tired. Both also drive me crazy!!!
The best way to keep on top of them is to test a lot.
We test every 3 hours per the endo. Jude usually sleeps right through it. Me, on the other hand, I feel like I haven’t slept in months! But, whatever it takes to keep my little buddy healthy!
I have noticed Jude getting super hungry when he is low. I haven’t noticed the breath thing since he was diagnosed. There wasn’t anything friuty about it. My poor baby had thrush and the worst diaper rash I had ever seen. I think that his vision might have been blurry or something, too, because he kept rubbing his eyes.
“I hate the world” lol I have to agree with that one 
In fact I have a few people in my life who will say “God! Is your sugar high or something???” when I start acting like a jerk And feeling hungry when your sugar is high is like such a cruel side effect isn’t it?
When I’m high, I get a headache in the back of the eyes. Strange I know but its the only way I can describe it.
Generally I don’t feel when I’m going low, but sometimes I’ll get an odd feeling in my legs orr my eyes will begin to ache.
For me, my eyes tell me everything ahaa.
but… don’t forget the butt! yeah that is defiantly a last resort…
When I"m low, I start to babble and don’t really know what I’m saying. I also get very flush, you can see me turn red from it. I generally start symptoms around 70, but if I ignore them at all they go away as I drop lower. My heart also thuds more, it’s not a faster heart rate, but i just feel it a lot more. My hands also decrease in sensation and I find myself making fists and shaking my hands to try and wake them up. I also don’t focus my eyes on anything, I just kind of stare off to the side
For a high, to me it feels like a panic attack, I get very fidgety and anxious and i cry, a lot. I get a mild headache and i get very very cranky from highs. My sugar tends towards low more then high, so I feel high by the time I reach 180-200.
