depression
"Diagnosed bipolar late 30's, lithium threw me into a clinical depression.  Was not hospitalized as I tried tricyclic after tricyclic, with the awful side effects, weight gain and almost a zombie, sleeping all the time.

Researching I discovered MAOI Inhibitors, was put on Nardil.  Had only 15 min. medication checks every two weeks.  At the first I asked, still depressed, "Will I ever be motivated again?", so weary was I of this horrid depression.

At the second medication check, two weeks later, my depression had lifted!  It kept me out of depression, functioning, and as close to 'normal', "whatever that is", for decades.  It saved my life."
