I had Covid 6/30/22 and was an avid walker (30 miles per week) and ended up fatigued and had SOB. I tried walking about a week afterwards of contracting it and could only muster 1/2 mile. My legs felt like I had added weights to them so I added ashawaghanda to my routine meds and kept taking antihistamines (Zyrtec in the PM & Allegra in the AM plus Pepcid AC 2x day), added BCAAs, extra protein and slowly started lifting weights. 3 months later I felt so much better and it continues on each month that passes. I only take Zyrtec now and an occasional Pepcid. Hope you continue to improve!
