Has anyone else had the experience of phenylpiracetam making them sleepy? The first time I tried it with the intention of getting some Economics review done and an hour later I was in bed, feeling really tired and wanting to go to sleep. I pushed passed it though and chalked it up to having other contributing variables.
Second time I tried 100mg of phenlypiracetam again a few days later, 12 hours after ingesting no other nootropics, vitamins or substances and noticed the same effect an hour after ingestion, I'm in bed feeling pretty tired and generally still fatigued with no change in body temperature (cold).
If I got around to doing anything technical on phenylpiracetam, perhaps I'd have better results as I recognize that It may help with more left brain tasks as my usual tendency of words spilling out of my brain and wanting to be expressed seemed to vanish, but I don't notice any stimulating effects on motivation, drive, energy or increased physical stimulation.
Somewhere I read that phenyl increases the amount of D2 receptors. This coupled with the fact that my dopamine receptors may be burned out from years of Vyvanse and Phentermine maybe contribute to this, but I don't see any anecdotal reports of Phenylpiracetam being anything but stimulating so I can't understand the paradoxical effects. Am I dosing incorrectly? Any ideas?
