The other replies are exactly correct. I was diagnosed a few years ago, and this was my primary symptom.

I waited too long after that symptom on-set, though, and ended up in the ER with heart palpitations, shortness of breath, and flop-sweat.

...and lemme tell ya -- when an overweight, middle-aged white guy stumbles into the ER sweating and re-faced while complaining of chest pain, those nurses haul ass. I went from fully-dressed at the entry door to shirt off in a bed with an EEG hooked up in less than two minutes. There was an IV in within 4 minutes, and the first blood test was heading to the lab within 8 minutes.

Please don't let your symptoms go as far as I did. You are likely still at the stage where you could lose some weight and get rid of your symptoms. Though I lost 15 pounds very quickly after my diagnosis, and lowered my A1C from 7.9 to 6.2 in 3 months, I still have to check my blood sugar daily and be super careful of what I eat.
