I had a horible time years ago with wd's from effexor and have been anti depressant shy ever since. I've got alot going on in my life right now and PTSD and I already take .5 of xanax 3 times a day. (don't wana go any higher) So... my dr gave me a script for celexa 20 mg about a month ago and said it would help with insonmia, anxiety, etc even if I just took it when I felt I really needed it, but everything online tells me you won't feel effects from this med until at least two weeks of treatment. So... Love my Doc... but could it be she gets extra incentive for prescribing this Rx?
