depression
"I was started on this med for depression from having no life from getting moderate-severe chronic fatigue syndrome. I can't say this has given my life back or anything but its the only thing that helps with my energy without causing flares like stimulants do. Caffeine is like taking out a loan I have to pay back with interest, if it helps at all. This is the only thing I've found that helps my baseline. 

I take 150mg a day in the morning. Many people find this sedating, but to me its the opposite. In fact, I can't consistently take any more than 150 because it ups my anxiety at 200mg and above.

I'm still disabled, but this is the only thing I've found that bumps my baseline up (and I've tried every supplement and med imaginable)."
