Help, how do I quit?!?

I've been doing a Colon Cleanse with B/P shakes for the last 4 weeks or so (yes, it worked!). During the last week of this I've gotten into an unpleasant cycle and want to know how to end it.

I am currently doing only one B/P shake a day (in the morning), and I don't eat very much during the rest of the day. What is happening is - I go for 2 or 3 days without a B/M and start feeling constipated; so I drink a laxative tea, after which I get Niagra Falls butt for half a day. Not pleasant!

Should I quit the B/P shakes entirely? I feel like I need the fiber, since I eat so little. I don't like using the laxative tea, but I like being "stuck" even less.

I should add that 1 - 2 BM's per day is normal for me. I have not suffered from either constipation or the runs before. Any suggestions as to how I can break out of this cycle would be much appreciated!
