I’d recommend cutting out carbs first, it helped me with my long covid tinnitus and fatigue.. my body was stuck in fight or flight mode from covid.. I was always exhausted, my muscles ached and at times I couldn’t think clearly.. my body was under a tremendous amount of stress for no reason.. so I decided to change my eating habits, find supplements to cleanse my blood and liver, reset my insulin levels.. then after 3 months of being mostly carb free, with eating fish a few times a week and salads, I moved to 16/8 fasting, then after a month of that I did a 24 hour fast and a month after that I did a 48 hour fast.. I upped my vitamin d to 6000 units a day liquid, no pill and take pine bark extract, garlic supplements and daffodil liquid twice a day, along with daffodil tea.. I also drink beet juice twice a week.. my long covid symptoms are gone and I feel like myself again.. I now do 16/8 daily, with a 48 hour fast every 45 days.. I don’t eat refined carbs anymore or sugar.. mostly meat, fish and poultry only with salads and cauliflower rice, avocado or beans.. I’ll use a wheat wrap if I want a sandwich now… also look into binaural beats to meditate, it will help you reset your mind and nervous system, it will help with your ptsd, while the fasting resets your body and immune system..
Not advice but shortly after I got Covid the first time, I was also diagnosed with mono. Ran a fever for close to two months off and on. A bunch of other symptoms and complications that led to an ER visit.
Update guys!!!41 hours in to my 3 day fast could use any motivational support because I’m having lots of intrusive thoughts trying to convince me to eat but staying strong because a lot of my symptoms have subsided!! Noticing a huge difference in my inflammation symptoms like glands and stomach as well as less overall uneasiness, definitely think it’s helping!! I am getting weird dreams and night sweats but my day is wayyy better
It’s possible that exercising again could have caused the crash. There’s a lot of stuff about post exertional malaise and how with long covid, pushing yourself is the last thing you should do. (Anecdotally, I’ve heard fasting can help, but ymmv) https://mecfssa.org.au/resources/pacing
