The brain fog was the worst. I had horrible insomnia too. I had to start on sedatives and anti-anxiety meds after I recovered. They initially put me on some poison shit like Xanax. I quickly switched that out for trazodone and medical marijuana. I could sleep but things were still way off.
I eventually got put on sertraline and adderall during the day, a 10 mg edible in the evening and I take a trazodone a hour before bed. I sleep better now than I have at any time in my life and I feel great. I don’t feel like I have the same raw cognitive capacity that I used to, but I’m attentive, productive and don’t struggle to perform basic tasks like I did after I got sick. Overall, I feel more capable than ever even if my mental processing speed is lower than before.
