Question on if i need a bowel cleanse

i was wondering how many of you think i need to cleanse my bowel before the liver?

i know you are supposed to do this, but i do not feel that my bowel is that clogged up. first thing every morning i have a pretty normal, healthy bowel movement. and some days i go twice per day.

i drink a magnesium drink called natural calm once to twice every day and this keeps me very regular. i am really anxious to do a liver cleanse but didn't really know if i needed to detox the bowel first.

i am on enough pills and didn't really want to do one of those Bowel Cleanse kits. i considered doing a juice fast for a week so i could clean out naturally, but i am afraid i would be too weak to do that and i don't think it is good to starve the body when your immune system is so taxed already.

i see a lot about these p & b shakes on here. what's that all about and how often do you drink those?
