depression
"This is one of the most under rated drugs for depression.  I found it myself and every time I mention it to a new doctor, they have never heard of it.  I am afraid they will someday stop making it, which would be a tragedy. It saved my life--multiple times--when NOTHING else worked.  I'd had every SSRI in the book thrown at me (because, OF COURSE if one doesn't work, SURELY another of the same type will).  No weight gain--actual loss. Pulls me out of suicidal despair within a few hours. I still have a bottle for emergencies.  For me, however, as a longterm treatment, it would start making me apathetic--not lethargic, just kind of nonchalant. After 3 days on it, I would want to quit my job. Fast acting, low side effects, mildly energizing."
