In the past couple of months i've been noticing that i get really shakey & lightheaded. Well, a couple of weeks ago i started doing it @ work, i felt like i had to run to the trash b/c i was going to be sick! i started getting really dizzy & i heard like a flashing sound in my ears. I started getting really hot & sweaty & then i threw up. After all of that ended i still would get really nauseous & hear the flashing sound in my ears, with feeling lightheaded. i didn't go to work the next day & layed in bed all day, but even while i was sitting or lying down i would still get dizzy & hear the sound in my ears w/ nausea. i've been told to get my sugar tested, but i'm not sure!
