I was in class the other day when a friend of mine commented that I am always "kinda shaky and cranky" at certain times of the day and it occurred to me that I am usually also very hungry at those times, but couldn't do anything about it because I need to concentrate in that class and can't concentrate after I eat.

 

I seem to get extremely sleepy after eating as well, to the point where I can drink a big cup of strong coffee with lunch and will still some times wind up falling asleep in public places. It seems to be especially bad if I eat a lot after not having eaten in a long time. I asked around and a couple of people told me that it sounds like I'm hypoglycemic, which is apparently linked to diabetes.

 

My dad was diagnosed as being borderline diabetic a couple of years ago, and apparently you can inherit a predisposition for it, so its got me a little concerned. I'm not really over weight though, and I never had any problems like this as a kid.
