I had Covid 11/2020; brain fog and fatigue slowly worsened but I woke up with dizziness/BPPV on a day in May 2021. It was debilitating, still is to some point. I did PT and it helped/helps. Meclizine did nothing. Sometimes antihistamines with a decongestant as well as Flonase nasal spray helps with the feeling of inner ear fullness. I do have to take zofran often enough, but it was almost daily! Staying hydrated was difficult, plain water made me feel nauseous. I have found Zevia Ginger Root Beer (trying not to consume too much sugar too!) or seltzer waters to drink help. Multi tasking continues to be a struggle that was not present prior to covid. My brain is just unable too much stimulation. I rarely drive with the radio on. Writing things down is a huge help! I recently started taking Provigil 200 mg daily, off label, to help with the extreme fatigue/brain fog. It has only been a short time but I do think it has helped with fatigue a bit but not with the inability to focus. My dizziness lessened as time went on and I have gotten more used to it. The eye exercises were a help for me in addition to PT. I hope you reach a better wellness soon.
