depression
"I was diagnosed with Bipolar disorder back in 2002 and I've tried every medication under the sun with no success. Then in 2006 my doctor tried me on Modafinil as add on to my other medications, I was really surprised at the effectiveness of modafinil. On my depressed cycle it made me get off the sofa and lessened my depression. During my mania cycle I would not have to take Modafinil. It is definitely a medication worth trying as an add to as add on."
