Duloxetine
"I'd been taking Cymbalta for about 2 years when I decided that I didn't want to pay $30/mo anymore, so I decided that I would wean myself off. I tried and I started getting the brain zaps, like lightening in my head. So I started back, slowly I just started missing a dose here and there until I was able to stop them without the side effects. I've been off for several months now and I've noticed that I've been in more pain and everything that was hurting me before has compounded. So needless to say I'm starting them back. Appears that I'm not going to be able to do without it."
