My detox enough?

I think your body will end up being the best judge of how much is enough detoxing for you-- but to me it sounds like you're doing plenty! I've personally just started doing foot bath detoxes and I noticed a difference in my overall health with that alone, so I think everyone is really different and it's going to depend on you specifically to figure out what's enough.

If you want to add something else simple to it though, my mom told me yesterday about how apparently you can slice potatoes and put them in your socks, like so they sit snug against the soles of your feet! Supposedly they help suck out toxins that way. She said onion will help too but.. you might.. not want onion smelling feet, haha.
If you're looking for something more to try, and can spare some potatoes, I say go for it. Definitely doesn't seem like there's any harm in trying that, aside from damp feet, haha.
