I'm on day 4 of a 16 day regiment. 4x4 3x4 2x4 1x4 daily. Is it ok to drink a glass or two of red wine whilr taking this med?

What med? Alcohol is generally not good for a person, much less for a sick person. You did not state the medication you are taking, however, my general advice is to stay away from alcohol or tobacco in any form.
