I’ve done a 24 hour detox of just lemon water with a little bit of Bragg’s apple cider vinegar. I always started my 24 hours right before bed so that way the first 8 were spent sleeping. And having to wait until dinner before you can eat again is pretty manageable even on a day you go to work. For the rest of the day, I just drank water but did the lemon/vinegar water 3 times a day.
And I felt better after wards.
