Six years for me. The LC clinic I had (in Montana) closed. I've tried various medications and supplements. The SHINE protocol by Dr. Teitelbaum seemed to help energy, but couldn't afford to continue. Nicotine gum helps fatigue. But nothing to help resulting blood disorders and compromised heart and lung function. I have at least five more years before I could even consider retirement, but I'll need to keep working due to financial pressure. After all this time, I don't anticipate getting my pre-covid stamina back. I do want to try fasting again for autophagy. Good luck, everyone. It's hard and depression from loss of health is also real. I am 61 and feel 90, although I actually know some 90 year olds who are in better health than I am.
