Been taking this for about 3 days now for treatment of anxiety/mild depression but at 3x the recommended dose (taking 3 capsules 3x a day). Didn't really notice any effects (positive or negative) while one it. Maybe a slight decrease in anxiety but nothing too substantial. I didn't take my dose this afternoon though, and about 8-9 hours after my morning dose I felt terribly depressed, far worse than I usually do (I often swing between "normal" and "pretty damn depressed" once or twice a day and today was particularly brutal).
I'm going to increase my dose to 12 per day for a week, starting tomorrow, and see how that goes. Tomorrow is also my first day of school, so I guess I'll see how this plays out in my college classes.
