After a night of drinking hennessy and cocacola i threw up this morning brown and black is that normal color or is it because of drinking dark liqour and soda i only threw up that once i kind of made it come out?

Black is not a normal color and can be due to bleeding in the stomach or elsewhere in the GI tract. The dark color can also be due to the color of the drinks consumed. If you continue to vomit a black color, you should get it checked since alcohol can cause GI bleeding. If you begin to feel sick, including lightheadedness, then you definitely need to see a doctor ASAP. Good luck!

Agree with Dr. Ferranti. You likely had bleeding in your stomach. Alcohol is a poison that never did anybody any good, ever, so stay away from it. It will destroy your brain cells, facilitate development of cancer in many organs, including breast, cause hepatitis, cirrhosis and pancreatitis etc. There is no safe level of alcohol intake. Quit while you are ahead.
