So.. I havent taken xans in like 5 months now, and I found 2 1mg footballs at home, and they are possibly over 2 years old, they were just left inside my old wallet for some reason. What are the problems and side effects of taking out of date xanax? Tonight I will have to work a lot on a project, like until past 2 am-ish, and tomorrow Ill probably wake up late and be unable to sleep early, so for me to sleep decently Id need to take those 2mg, is there any problem since they are pretty old and sort of unproperly ''stored''?
