Fluoxetine
"20mg a day changed my life. 
Head pain due to stress and anxiety is gone when taking this tablet and also OCD in the form of dermatillomania (finger) completely better.
I had this for about 3 years and decided to stop, the weening off was very tough, I had a good month or two of hit sweats/shakiness and agitation. However I went completely back to normal for over 2 years after that. I have now restarted Fluoxetine/prozac due to having a very stressful year and struggling to get by day to day. 1st pill and I am mellow as a mellow thing once again, goodbye stresses!"
