My Dr gave me a script for Lexapro amd Xanax for my anxiety. I have not taken a xanax, but last night was the third night i took the lexapro, and i felt fine, and went to bed, and woke up at 2am gasping for air, and choking on v**, i ran to the bathroom, and nothing happened..so i sat on the couch for 4 hours scared to death, and i took a heartburn pill and a zofran and half a promethazine after it happened. I dont know what to do, i way to scared to take another pill since thats my greatest fear, but at the same time, i think they would have helped me...so confused now.
