Hi. I know the feeling you have, the "unclear" one. It feels just like residual brain fog. Sometimes it is better sometimes worse. For me, it also sometimes prevents my eyes focusing especially on the objects that are closer.
I have read somewhere that curcumin helps restore the H in the HPA axis. The root cause of AF. I also check here what people say about curcumin. There was a reference on an article that talks how curcumin affects hypothalamus.
I tried and it works, even vision improved.
Don't try cheap version because it would be difficult to say if it does not work for you or just poorly absorbed.
