I have tried many different combinations of piracetam, pramiracetam, oxiracetam, aniracetam, and alpha-gpc. The doses that allow me to sleep the best are:
<2.5g piracetam
<.8g pramiracetam
<.2g oxiracetam
<.2g aniracetam
Although these doses allow sleep somewhat, I can't really feel the effects unless I go above these doses. But, when I do, I cannot sleep at all. I have to take at least 30mg melatonin, 2 grams phenibut, or 100mg benadryl. When I take all these sleeping pills It makes me hungover all day the next day and completely outweighs and nootropic benefit.
Maybe there is something wrong with my brain chemistry. Something I noticed that seemed a little weird is that I sleep somewhat better when taking 10mg piracetam right before sleep. I am not sure what this is causing on the brain's chemistry. Also, I noticed that I have a really slow caffeine metabolism, such that if I drink coffee at 6am, my heart will still be racing at 10pm.
Could the slow caffeine metabolism show the same effect in slow racetam metabolism? What is everyone's experience with doses that allow them to sleep?
