Escitalopram
"I went through a life threatening situation. I couldn't sleep, eat nor get my body out of flight fight mode no matter all that I tried (yoga, meditation, accupuncture, herbal remedies) I got sick and tired of the every day battle with my mind and body so I sought medical help. It was the best thing I ever did! Cipralex took 6 weeks to kick in @5mg dose (I took clonazepam to counter the increased anxiety side effects for first 2 weeks). I got brain zaps, spacey headed, sleepy and had dry mouth. It all went away within 3 weeks. I Took it for a year.. A slow wean is key to minimize coming off side effects. I did it over  4 months. It takes time to build up on your system, don't give up as weeks 1-4 are rough. After that, you reap the benefits"
