Hi,
I've been taking piracetam, vinpocetine, and choline for some weeks, and I have been feeling "down" in overall mood. I am usually somewhat manic at times (not clinically so, however), and I've noticed that this has decreased and I have been feeling very emotionally flat.
I read in the following website (http://nootropics.com) that nootropics can affect mood negatively by disturbing the balance of acetylcholine and noradrenaline in the brain. Anti-depressants lower acetylcholine, nootropics raise it. This is the simple explanation. There are more details in the webpage I have linked.
My question is: has it actually been proven that nootropics that raise acetylcholine levels lower mood or cause personality problems like stress intolerance? Has anyone here felt such effects after using nootropics? If so, was there a way of preventing this while continuing to take the nootropics?
Thanks,
Andrés
