FWIW - Kid#2 was doing foot soaks (epsom salts and hydrogen peroxide) 2-3 times per day for awhile. We quit them because we really weren't seeing any benefit for him.
For Kid#1, he has done the baths for numerous years now. He use to do it daily, but now he does it occasionally. He finds them "calming/relaxing".
For me, I do them occasionally as needed/desired. I can't say that I really see much benefit honestly. I do them more so for occasional pain relief (not sure it really helps). I do think they are great just for a break at least.
Kid#1: Extremely sick for several years, very difficult to treat, but much better lately!
Kid#2: Very sick now despite being treated for years, very bad year
Kid#3: Doing great, minor relapse, but great again (ironically had least and shortest treatment)!
Me: Adv Labs positive 2016 (suspected I passed to my kids) - not as sick as others, mostly battling fatigue, kidney, heart, and yeast issues
