You can just tell them that alcohol isn't ok with the medication you are taking.....they don't need to know WHAT medication it is...& it's really NONE of their business......sadly, peer pressure is a pain.....when you get older...I hope you are able to outgrow that effect......I started young with not allowing it to bother me because my values weren't much like the peers around me in the first place & I liked my values more than I valued the opinions of my peers....so it was no big deal.

Don't let the pressure get to you
