here's a respected site to learn about hypoglycemia:

But hypoglycema isn't an disease (like diabetes is) but just an indication you have a problem and should see your doctor to figure out exactly what is wrong; there can be lots of causes.

You don't ever want to "spike" your sugar; so caffeine, sugar, etc. should be balanced out throughout the day; no coffee and danish for breakfast and nothing else until lunch sort of thing or my husband's favorite, a snack of cake or pie just before going to bed late at night.

Just work on eating "better" and things can correct themselves. Very hard if you're a student though, I understand; my group therapist was into my having hypoglycemia when it was just coming into vogue in the 1970's but I was in my 20's and lived on coffee, beer, and potato chips for 5+ years.

One thing I like to do now is eat an apple a day. That really does work :-) and an apple mid-day will wake you up better than coffee (I accidentally tried it and it works!) and you can carry around carrot sticks/veggies in baggies, etc. It use to be, don't know now, but "nuts" were the thing to help with hypoglycemia, when the energy was lagging, etc. you ate a handful of peanuts or something. I have an unsalted trail mix I like with sunflower, soy, peanuts, hazelnuts, raisins, etc. that I get at my health food store and eat too much of right away so I feel sick, LOL.
