Have you considered gaunfacine? https://medlineplus.gov/druginfo/meds/a601059.html

I had long suspected I had ADHD. After covid, my brain became wrecked. I wanted to go with something non-addictive due to my checkered past. Easily would recommend, as long as you don't have terribly low blood pressure. NAD.

Another thing to try is NAD+/CoQ10 supplements. I had some brain fog after covid (I'm officially diagnosed) and NAD+ seemed to help a ton.

I had researched the brain fog with covid 19 and found a lot of research pointing to NAD+ / mitochondrial disruptions as source of brain fatigue [eg 1]. NAD+ supplements are well studied for anti-aging too. So it seemed to have a high probability of helping.

How to increase one's NAD+ levels?

[elcritch]

The NAD+ supplements can increase it according to a few research articles I've found. IIRC, it's like 10-20% increase in some cases. I also added CoQ10 as it works together with NAD+.
