Drunk the night before then in morning drunk pepto bismul then next day dark green stool. Is that bad?
Green isn't bad. But getting drunk can be. Pepto bismol (bismuth subsalicylate) routinely turns stool a very dark green which can even look black. It can do the same to your mouth or tongue. This is totally harmless. However, drinking to where you're drunk isn't harmless, and you should consider cutting back on alcohol, especially if this is a regular occurrence.
Pepto bisul. Peptobismol usually colors the stool greenish black so that probably is no problem. However you seem to be having a lot of alcohol and that may be a problem of addiction which can be severe. If you are indeed getting drunk very often, it would be a good idea to talk this over with your doctor to see if there is a problem.
