I don't want to get too personal or anything, but I'm a fan of the good old fiber blend on a Sunday night. Why?
It's a great way for me to kick-off to the new week and um...just to keeps things moving! :)
I prefer Tahitian Noni's Juicy Orange Fiber Blend. I take that in like 10 oz of water, then guzzle another 10-20 oz of water right afterwards and let nature take it's course.
