I have been diagnosed with bipolar disorder and have tried a number of medications at different times, usually a combination of 2 or 3 of the following: lithium, prozac, lexapro, seroquel, abilify, risperdal, klonopin, vistaril, zyprexa, ambien, rozerem, & depakote. Zyprexa, Benadryl, Depakote, and Seroquel have caused me to twitch and feel like my skin is crawling an hour (or a few) after I take them.
