if you live in the u.s. in an area where the public water suppply is fluoridated and chlorinated (i.e. most of the u.s.)
then go out and get yourself a good water filter for bathing. this is very important.
once you do this, if you ahve a.f. then pour a large box of se salt or kosher salt into your hot baths. you will likely not be tired anymore after bathing.
