Stomach, Ulcers, Gastric Bypass Forum - Dark Stool, Mild Abdominal Pressure/cramping

So, i'm 19, in college, and I don't drink often. (really, I don't. Once a week at most, and usually less frequently than that.) however, I drank very heavily two nights ago (quite a bit of liquor, if that makes any difference), and I woke up the next morning feeling absolutely fine. It's worth mentioning at this point that I almost never get hangovers.

Anyway, since the binge, i've had fairly frequent (3 or 4 times a day) bowl movements that appear a very dark brown or blackish color, which, based on my research, seems to be the result of some sort of bleeding (there are also very, very small spots of blood on the toilet paper). I also have some pain on either side of my abdomen that feels like a mild cramp, so much like a cramp, in fact, that the pain usually goes away for awhile after a good stretch. Yesterday there were some slight bouts of dizziness, but those seem to have gone away.

Again, allow me to stress that I am functioning completely normally and still going about my day-to-day routine, and that all of this is very mild.

I can only assume that this is related to my night of heavy drinking, as that was the only variable that changed, and I know that alcohol can cause stomach irritation. I don't have the greatest diet, being a college student, but this hasn't much affected me in the past. I feel like i'm worried about this than I should be, but I was wondering if anyone had any insight to offer on this matter.

I don't plan on seeing a doctor about this, as it's really not that bad (though I won't be so foolish to continue ignoring it if it gets worse), and it's a huge pain in the ass for me to see a doctor, given that i'm off at college, especially without my parents finding out about it, as i'm still on their healthcare insurance.

For now, i'm eating an easier diet and drinking lots of water and some apple juice, and hoping this will clear up. I also do not plan on getting that wasted again; it's pretty safe to say I learned my lesson.

Still, though, to assuage, or at least inform a worrying mind, does anyone have any input or advice?
