Hi and welcome to HCM.
You had beer for first time and vomited, this happens in most people first time.
Drinking alcohol heavily can irritate your stomach's lining, causing nausea
. This is a protective mechanism your body uses to warn you to stop taking in toxins. The best cure for this problem is to stop drinking
You might also had gastritis
, which have induced vomiting. But if this happens every time you consume any alcohol products then its need to be evaluated and its better to visit a doctor.
My suggestions is Try not drinking alcohol, smoking
, or taking any nonsteroidal antiinflammatories like Advil/ibuprofen
and see if your stomach calms down
