drinking while on zyrtec?

I’m(f22) on zyrtec prescribed 1 per day or every other day 10mg but i want to drink with my friends and enjoy our time like everyone else. how can i drink in a safe way in relation to my situation? obvi i won’t wash one down with alcohol maybe if i take it in the morning and drink at night but won’t it but too short time between the night and the next morning? I don’t want any bad reactions or to drown in my own spit while i sleep so if anyone has tips pls lmk
