Black stools: After drinking is an ominous sign for a gastric ulcer or gastritis, aggravated by the alcohol, leading to bleeding. The blood turns black when exposed to acid in the stomach and hence makes the stools black. Stop drinking! and go see a gastroenterologist to make the diagnosis and get you on a treatment plan before you do some serious damage.
