What can i take to make me stop feeling sick and throwing up after drinking alchohal?

Alcohol: The obvious easy answer is to stop drinking alcohol. I'm not one to quote the law a lot, but I notice that you are only 17 years old, too. I am not aware of anywhere it is legal to drink at 17. In my experience, many alcoholics start drinking in their teens as a way to self-medicate and try to escape problems. I'm worried about you. You should see a counselor or therapist, and a doctor.
