I only use it for extermely intense study sessions. It has, like most smart drugs, no periphial stimulatory effects. You don't really get an amphetamine-like rush of thoughts. Instead, you'r mind becomes absolutely, almost painfully, clear.
Memory retrieval becomes much more fluid.
Reading becomes much more of an easy and passive activity. I use pramiracetam in combination with vinpocetine. I am afraid I cannot compare it to aniracetam, because i have never tried that. However, I will describe my pramiracetam benefits in the hope that that helps some. I am pretty bad about following conversations, and coming up with the right words when I am talking.
