Dear fizzlex, If i were you and had to work i would definitely not attempt the cleanse unless it was a weekend, because when i did the cleanse diet, i nearly passed out, and needed sleep, sleep sleep. Be careful. I’m vegan so for me the choices of protein are even more restrictive, but if you aren’t vegetarian/vegan, you can eat chicken, beef, wild salmon, etc.is listed on Lisa’s what to eat and what not to eat lists. I recommend reading and re-reading all the info on this site to become thoroughly familiar with it so it becomes second nature. It really is a lot of information to digest. One day at a time.
