i have anxiety and was on lexapro.. and you know what i don't really know if it makes a difference. I think it all depends on you and how your body reacts to it. I never had attacks while high until i started other drugs... been clean now for 3 years and they went away.. this is all when on lexapro.. so like smokinbomb said only one way to find out.. toke up ! give it about 3 months to be entirely in your system. My doc said a month.. but it seemed longer then that.
