Okay, I figure you guys might be able to shed some light on this, since every other person has some medical troubles/experience.
I haven't been eating as much lately; just plain lost my appetite, for the most part. I lost a decent amount of weight; I'm about 130 lbs. now, give or take a few. My girlfriend has been helping me remember to eat more lately, and all day I've been very tired and get dizzy quickly.
I have two theories; one is the obvious answer that I need to eat more. But the paranoid side of me is yelling that I have type 1 diabetes. (You know how once you get one of those thoughts in your head, and it won't go away, even though you know it's probably not true?)
Anyone have a clue? I'm willing to take all the heckling for a little peace of mind.
