That is scary! I have the exact opposite issue. My alarm goes off and I know know know I am not low. Check my sugar and it’s fine. So strange. Seems to be happening more of late.
That happens to me as well. Which is also why I get annoyed at the commercials for Dexcom that say “No finger sticks anymore.” Or “Zero finger sticks.” When in fact I do more finger sticks now since Having Dexcom in response to alarms for lows and highs many of which turn out to be incorrect, and some of which turn out to be correct. But I don’t know unless I check. I also don’t know at mealtime if it’s in fact correct, unless I check, so unless I check don’t know if I need to add an extra unit or two for correction if it should happen to be reading lower than it actually it by a lot as that has happened on a few occasions. I like to keep a tight control on my level so don’t want BG higher than it should be. Thus LOTS of finger sticks. And the Dexcom manual even says to do finger sticks before any treatment decisions so there you have the truth! Just wish they would be honest in their advertising. Even my PCP said, “Why do you need all these test strips and lancets when you have a Dexcom?” And so I had to explain it to her. So thanks Dexcom for even disinforming our healthcare providers. Makes me wonder if some people have trouble with their insurance covering those supplies for the very same reason.

Having worked in product development, the problem is sales, not engineering. Sales tends to be ignorant of what the product does, but confidently spout their ignorance.

Often I don’t stick my fingers anymore on dexcom. Only if I feel different from what the reading is. It’s been so spot on lately that I just check it less and less

Annie, I tried to reply. But now it doesn’t look like my reply was addressed to you, but rather just posted generally. I don’t know. I hit the “reply” to you button first. So this is a test to see if this one actually replies to you or not.
Sorry. Still new here and trying to figure things out and having glitches I guess because I’m using this on my iPad, not sure.

That won’t work for me. I can’t usually tell when I’m too low or too high. I mean I’ve been below 50 and didn’t feel it. I do however, also have other symptoms from MS that may also mask it or just interfere, I don’t know. And I never felt any different when high except when it was exceptionally high above 300. Therefore, for me personally, how would I “feel” anything different if it tells me I’m 113 but I’m actually 143 before a meal? 113 would be fine and require no action. Whereas 143 would require me to add an extra unit of Humalog to my meal dose otherwise I’m going to be too high for sure.
But I’m glad it works for you! I say count yourself lucky!!
I had lost my glucose awareness a long time ago, but after I was on a pump for a while and my control tightened, I started feeling it again.
I feel weird tingly all over and my jaw hurts when I’m high.
When I’m low I feel sweaty and panicky and confused.
If you can tighten your range for a period of time your body gets used to it, then you start feeling symptoms when you leave that range. So just know it can get better.

I’m in range 91-95% according to Clarity month after month, year after year for 3 yrs now, with standard deviation of 22-28 again consistently. My A1c has been 5.2 for two yrs and 5.4 for the year before that. So I kind of thought I was rather reigned in. No?
I already have weird tingling and weakness in many parts of my body, along with severe fatigue and headache from MS. And those MS symptoms are with me daily with fluctuations within a day and from day to day, but there everyday, for years before diabetes and since without change.
Well then unfortunately, you won’t likely bet your awareness back with better control. Cgm is your best friend

Is anyone getting more than 7 good days out of a Dexcom sensor? For the last 4-5 sensor placements-all on abdomen as suggested-I have only gotten 6-7 days out of a sensor before getting wonky readings. For example I just received an alert that BGL was 48 and falling fast. I feel fine, so did a finger stick and the result was 139 mg%! Also happens that the last 3 days or so of each sensor session have many missing data points and not infrequent “wait up to 3 hours” messages. It’s a drag to have to keep contacting Dexcom support.
@Bob10 I haven’t in at least month now, but I have had that happen many, many times after 6 to 7 days. I always use my abdomen. They are always good about sending a replacement sensor. But yes, it is especially bothersome when it happens at night and I end up most the night between alarms, finger sticking, calibrating, rechecks, note taking, and finally calling Dexcom, then changing sensor, and sometimes calibration after that. Makes for a long 
night.
Going fine right now. 
I got 10 on my last one but it was just starting to act funny.
7 days is where I start getting wacky readings, false lows and the “wait up to 3 hours” message. I have had it happen with one lot number and another with the same lot number work for 10 days. I wonder if it is a problem with an individuals unique biochemistry.
There are some who restart sensors as much as 3 times, and others are like you and me, lucky to get through 10 days without annoying problems.
As a retired electronic tech, I chalk it down to FM (the F word magic).
I had really good results placing sensors on my triceps area about 6 times. Then I got the dreaded drop outs and false hypos. So I went back to the abdomen, placing the sensors fairly high.
I know I have scarring from a couple of surgeries, but I can’t see it.

As a different perspective, I’ve had very good results with placement around the upper arms. 10 days, accurate, no pre-soak needed. For over a year now
Do you place them in the side and front? I’ve only used the back, where I have a lot of lose skin.
I put them on my arms and get 25 days on average on an unexpired one and 15-20 days on ones that are expired by a few months. I will only get about 14 days on ones that are expired for almost a year. But on a current sensor I have gotten as much as 45 days, hence why I have a supply of expired sensors! I actually like restarted sensors better.
But I also know that if my transmitter is nearer it’s expired date time on the box or after, the sensor won’t last as long.
I don’t have much loose skin but enough, I guess. I don’t go all the way around the back but most of the way and about a hand’s breadth below the shoulder.
I switch arms each time.
And I occasionally have reused sensors, usually get an extra ten days use from them. But have challenges taking the sensor out, even with ole test strips.
