I threw up dark brown stuff after drinking 2 days ago i had to throw up. not because of dizzyness. i produced high amounts of salvia and then threw up. at first there was small splash of dark brown stuff then it came out normal. i feel ok/good?

That could be dry blood. It is good that you feel well and it stopped but if this recurs seek attention of GI specialist and watch the drinking.

Alcohol is a poison that never did anybody any good, ever, so stay away from it. It will destroy your brain cells, damage testicular cells that make testosterone, facilitate development of cancer in many organs, cause hepatitis, cirrhosis and pancreatitis etc. There is no safe level of alcohol intake. Quit while you are ahead.
