Serious side effect report: possible neuropathy?
So, after my first experience with coluracetam (10mg sublingual), I experienced major facial flushing. It looked and felt like sunburn, and I read a report of another person experiencing it even more severely. I did not revisit it for several months after that. When I did, I kept the dosage low. I responded very, very well to it. 5-6mg orally was better for motivation, energy, concentration, and improvements to working memory than anything I had tried. Prior to this, the only noots that had benefited me out of a very long list were noopept, NAC, and SAM-e--all of which I eventually discontinued due to lack of consistency or due to mild but annoying side-effects.
Several weeks in to my intermittent use of coluracetam, I developed a strange sensation that was most intense in the tips of the fingers of both hands and faded gradually up to my elbows. It was a strange tingly numbness. Worse--and this is hard to describe--it was quite unpleasant when I touched things with my hands. Just slipping my hands into my pockets caused the unpleasant shudder-provoking sensation to shoot up my arms. It was exactly the same feeling that I get from the vibrations through my hand when I drag my fingernails down a chalkboard. All the time.
I hadn't changed anything else in my regimen, so I eliminated coluracetam. The unpleasant senation continued unabated for another four weeks before it for the most part subsided, so I assumed that it was caused by something other than the coluracetam. After another month or so, I took another dose of coluracetam and had no negative effects. The following day, I took another dose. Within a half an hour, the sensation returned, and at the same intensity it had months before. It has been three weeks since that dose, and the sensation is still mildly present.
It's not conclusive, but it's clearly been concerning for me. I thought I would share here and create a separate thread for this experience to let the community know.
