@Mallard6146 Interesting to see another person dealing with long covid here
I did a protocol of nicotine patches for about a month and it temporarily took away all my fatigue and PEM. The only downside is that it sadly started to give me sleep issues and insomnia so I had to stop using them. I find that either smoking cigarettes or using snus give me better results for eliminating my fatigue and not giving me as many sleep issues as the patches do.
Although everyone is different you should definitely try it and see how you feel since I see a lot of success stories coming out of nicotine use for long covid.
