Acne gets worse with P&B shakes, what should I do?

Hello,
I am 32 yers old and have had Acne (cystic) since I have been 20. Took Accutane twice, it helped but the Acne came back WORSE eache time after about 1 year. the pill helps a little, but I don't want to take it (stopped 3 years ago). I start living with it, it is very hard.
I eat healthy, all organic, a lot or raw foods, but I have a really hard time cutting down Sugar and bread and coffee. I did P&B shakes (dr Sonne) 3 Months ago, fo about 2 Month and my skin got crazy horrible worse then ever. It was better when I stopped. Now i started the shakes again, because I really wnat to do a cleanse, I hope it will make me feel better and my skin will get better. But now it looks the Acne is getting worse again. I was hoping to do the shakes and then do the Liver Flush (have never done it before).
Should I stick with it? Should I stop right away? My face is very inflamed and red. It hurts. I need some support. Every bit of motivation will help.
--thanks in advance--
