Can i drink a few beers while taking antibiotics?

I was recentely prescribed 2 antibiotics (cant think of the names, dont have slips with me) and have been on different ones before this. Doctors have always told me not to drink while taking them except for the most recent doctor ive been to who said it was fine to do so.

Ive now been scouring the net looking for similar answers but only get more confused with finding most people saying “NO DONT!” or saying “Yes, its fine!” What does the Fluther community say?
