Do you have an HEPA air purifier? That will help while you are indoors.
Curious if you’ve fasted before? I keep seeing posts of people going for 10+ days which is very series and should involve research and preparation and really it seems best to work up from time frames which I don’t know if people are doing.
Dry fasting might be the best thing one can do for health but should be taken very seriously. Is akin to having surgery.
