Just wanted you to know I’ve been dealing with post covid since last October. It was severe at time. I even had a CRP blood test that spiked to 96! Several MD360 visits, 1 ER visit and slowly getting better . Used an out of network dr who used repurposed drugs that really helped. I had a breakthrough last week with brain fog. I decided to take 10mg of my older adderall I had for add/adhd and it completely cleared up my brain fog. I’ve been taking it now for a week with excellent results. I’d encourage you to ask your healthcare provider if this is something you could try. My hearts in really good shape now so no concerns there. I hope this will help someone out there who’s suffering like I have been. Good luck and don’t give up!
