Alcoholic drinks and Invisalign: Do I take my trays out for every drink and brush after every drink?

I really hope this isnt a dumb question, but I have to ask. I start my invisilign treatment om November 28. The question I have is if I go out for a night with my friendsfor drinks do I take my trays out for every drink and brush after every drink???..or since I have to wear them for 22 hrs/day do i leave them in while I imbibe (lol
