Part of the detox program is to cleanse you body and get out all the bad stuff we store. The only way to get that out is to go to the toilet so if you are going that much, then it is working. You may even find that you have funny shapes and colours coming out, try not to worry.
If you start to have pains, then you should consult a doctor.
i did a cleanse last year and loved it.
Good luck
