Most of the time, constipation is caused by a food intolerance. I, for example, am highly intolerant to wheat and when I eat it (even a small piece of bread) I get constipation for days on end.
You need to find out what is causing the constipation and then eliminate it. Mostly this can be done by an
Elimination Diet which, however, is a lot of work and it is easier to have a professional help you with it. There are some other ways of testing for intolerances and allergies, however they are not always 100% correct.
I don't see any reason why you should not be able to do the
Master-Cleanse again, however, at the end I would take the opportunity to check out what's causing the problems.
