As a sorority girl in college, I go to parties quite often and have a fair amount of alcohol usually. I started taking lexapro last summer 2014. I blackout almost every time I drink, and I couldn't figure out why. I started tallying my drinks so I could examine it in the morning. Even on nights I didn't drink that much, I still got incredibly drunk and usually blacked out. I do think it is the lexapro. I was really scared for awhile but anyone else wondering, rest assured- ITS OKAY. I'm glad to know other people have the same side effects!
