Did you say you have tried/tested this stuff?
http://www.starstuffuk.co.uk/ I used it before with great effect!!! felt more energized, better sleep, didn't suffer hang overs, happier, and every now and then i'd get what i can only describe as a burst of excitement or a 'wave of euphoria ' good stuff!
Stopped using cause of money and because after about 3 to 4 months of using it i stopped feelign the effects, maybe they just just not obvious because i was used to it, but i could not 'feel' it working and money was tight so it went....
