Duloxetine
"I started taking Cymbalta and I noticed a difference immediately!  I felt more relaxed and happy in general.  I take Lamictal for Bi-Polar disorder and after finding that medicine alone not being enough, my dr prescribed Cymbalta.  I've been in a pleasant mood with my family, friends and at work.  Not stressing out about leaving the house or having a busy schedule and getting anxiety about it.  It has also helped with my lower back pain I have been dealing with the last 3yrs.  It's only been 2 weeks and the only thing I can say is, I seem to yawn a lot and have less of an appetite.  If it messes with my sex drive and lowers it... I'm off it."
