^ great post.
Piracetam does not 'restore' serotonin receptors, but it does move the existing supply of serotonin and dopamine preferentially into the highest cognitive center, the prefrontal cortex.
Meaning the surviving receptors will get a lot more action.
It also increases communication between the two hemispheres and bloodflow to the corpus collosum that connects them. In high enough doses, it protects the brain from ischemia - meaning it improves blood perfusion and oxygenation.
It can diminish MDMA if taken just prior to it.
Several hours, perhaps a day or two is required for the effects on the PFC to take place.
And they are quite profound.
Piracetam makes one hell of a big difference in my brain function, but the benefits are not permanent.
Within weeks of withdrawal I begin to feel the return of cognitive decline, and especially emotional anhedonia.
Or at least I used to...
Things are improving and I haven't used the stuff in about 5 months.
But I'm sure I will again, especially for any future rolls that I might attempt.
But Sam is wise.
Only TIME allows for recovery from MDMA.
Lots of it, based on your description.
