For the last two months I have had a terrible time sleeping. I had blood tests run to find out if there was a medical reason, with no results. I'm not stressed out or go to bed with my mind pre-occupied with problems. The only thing different I have done that I can think of is go off the anti-depressant, Effexor XR. I can't make a connection because I never took them at night, only first thing in the morning. If anyone has a similar problem, please let me know. My doctor put me on Ambien, but I don't want to rely on sleeping pills the rest of my life. Thank you.
