During a recent period of "not feeling regular" I picked up some Metamucil at a local drugstore. I bought the orange-flavoured variety; it tastes like grainy Tang. The directions suggest starting with a single dose for the first few days, then ramping up to three doses per day. I went straight to three per day and during the initial twenty-four hours nothing happened. On the second day my bowels unleashed the mother of all food babies (virtually stink free, too). I felt like a million bucks. Highly recommended.
