pinkanga -- did you take powder piracetam? or the nootropil? The powder appears to be *far* stronger from personal experience
Next time try taking 4g with 4g of choline. Piracetam and choline are massively synergistic. I seem to recall a study that, piracetam became effective at 1/10 the usual dose if given with sufficient choline, though I can't remember where. I do think it was on pubmed though...
A lot of people have observed that piracetam works best when your brain is already impaired by something... whether that's a hangover, tiredness, stress, etc. When I was doing shitloads of pills, I found piracetam to be invaluable. I haven't done any pills in a while now, and I still notice piracetam, but not anywhere near as strongly.
