Apple Fast Tips/Strategy

Hey community. I am doing the apple fast starting tomorrow. I have been on this program for 2-3 months yet i have been dairy free for 2-3 weeks. My face is just full of underskin bumps and im sort of stumped about this. So i decicded to do a fast because i know that my gut/digestion is horribe. Im pretty sure a fast will be very helpful in clearing my acne because it makes the body be able to handle more toxins. Although I may be wrong, and if thats the case go ahead and tell me the correct information. Ive got a couple of questions though. On the fast, can i still take plant enzymes, multivitamins and omega 3's? And The last thing i am concerned with is figuring out how and what to eat right after the fast. Any help suggestions would be helpful. Thanks Guys!!!
