Welcome to the group! Try checking out the vitamins and supplements regimen sticky for starters. I wonder if taking a quiet walk outdoors may be helpful with your sleep troubles. A little exercise can go a long way for sleep, but keep it light, you don't want to overtax your brain.

My symptoms are different from yours but I have anxiety and depression. My neurosurgeon has me on a regimen of vitamins, minerals and a couple of other supplements. The regimen works, no brain fog, anxiety or depression and no drugs. That is definitely something worth investigating.

Keep checking here, I'm sure more good advice from other members is forthcoming.

Good luck with your recovery. Get lot's of rest if you can and don't over do it.
