I just thought the suppliments would generally do me good, maybe improve my motivation, focus, energy levels etc. Kinda similar to what I wanted pirecetam to do, thought maybe this other stuff would give me a kick in the right direction. The St Johns Wort and Vitamins etc I just thought would generally give me a mood lift and might make me feel a bit healthier / better and maybe slightly more excited about university which is the main reason I want my motivation levels increased.
Not ruling out the anxiety thing as I do occassionally get mild anxiety now again, nothing major.
