Brain fog from cannabis use/withdrawal?

I smoked weed daily for two years and quit cold turkey 3 weeks ago. I still wake up with awful brain fog that persists until a few hours before bedtime. I have Semax, Selank, and noopept that I started taking 2 days ago. My reasoning behind choosing this stack was that Semax and noopept seem to help the brain rewire after injury (in my case heavy cannabis use), and selank to help with the anxiety that I used to use cannabis for in the first place.

Does anyone have any advice, input, or commentary on this approach? Should I dose the selank in the morning too or just at night to try and relax? Cycle advice? I’ve seen a ton of conflicting info on this sub and on the internet in general
