Metamucil is great as a daily preventative, rather than a treatment. I've switched brands though - changed to Fibersure (because it was cheaper) & I like it heaps better than the Metamucil. My preference for Fibersure has nothing to do with the results - they both work fine - but the fibresure has a MUCH better texture - almost completely dissolves, rather than leaving gritty bits. It's all natural too (whereas the metamucil smooth texture uses artificial sweeteners - which I'm trying to avoid in pg).

Hope that helps!
