I haven't been taking choline, and overall I haven't noticed any effect with Piracetam by any metric I'm taking except that I've been late for meetings and classes much less than normal (this has always been a big problem for me.)
I'm coming up on two weeks of use (1.6 g per day), so I expected more effect by now. I'll probably try adding choline to my diet and I'll see if that makes a difference. In any case, I'll continue taking Piracetam until I run out since I don't mind swallowing pills anyway.
Since I'm about to start using Modafinil, I might not be able to distinguish whether choline makes any difference.
Modafinil is something I've wanted to try for some time. How did you acquire it?
Many people on LW have expressed interest in nootropics and cognitive enhancement. However, since people are presumably interested in the long-term efficacy, side effects and withdrawal symptoms of using various supplements, open-threads (which quickly become hard to navigate and only last a couple weeks anyway) are a sub-optimal place to discuss the topic.
So I thought I would create a permanent area for people who want to discuss the topic long-term.
