bipolar disorde
"I have been on and off this medication for nearly 10 years and it has been generally helpful most of the time. It takes a long time to titrate up, and the there is a very specific dose that is different for everybody, but once you get it right, the medication is remarkably helpful.

In my experience, it all but eradicates Bipolar Depression and it reduces the severity of Bipolar Mania. 

Don't worry so much about the rash if you're a hypochondriac like me. "The Rash" most likely would only be limited to mucus membranes around the eyes, nose, mouth and genitals.

One thing I should add: over time, the medications seems to lose effectiveness and if you frequently discontinue, this effect is exacerbated. Eventually I had to add lithium."
