Psyllium and bentonite cleanse questions

I've decided to go with the PB shakes cleanse method but I have no idea what to expect. Is it a bad idea to take this when immediate bathroom access is not always an option in my working conditions? Are bowel movements going to increase or decrease or does that just depend on my body/diet? Am I going to experience addition bloating to what i regulary have, or is this another unknown? I understand I need to take Probiotics for this cleanse, is Acidophilus all I need? and how often and in what quantities should this be taken? Should I start the shakes on a weekend just in case my body has a bad reaction, or should it be safe to start any day. One last question, is their a chance the cleanse will cause any irreversible symptoms meaning is it perfectly safe with no health risks involved? Sorry for all the questions, just things I really want to know before I start. Tweet
