@Gina I wish you luck! I've been fasting for a few years now intermittently. Most I've gone is 28 days. May be a good idea to get some electrolytes in the form of taking pottassium, sodium, and magnesium. Definitely lots of head clarity and a big boost of energy will come your way. Here's a post I made with my milestone: https://www.reddit.com/r/fasting/comments/9ksdcm/wrapped_up_my_year_with_a_21_day_fast_and/?utm_source=share&utm_medium=web2x
@darthwayne 21 days?! Damn, that's insane.
Do you perhaps know how to best take electrolytes? Are there supplements for that?
@Gina I take some himilayan salt, potassium complex, and magnesium tablets, usually just once a day. You should be able to find these all at your local grocer.
@Gina Also, the biggest mind over matter trick I can give you to endure is to just keep yourself busy.
