I'm probably not the best person to ask... I took Metamucil on and off for years. I was never able to get into the habit of taking it daily because it gave me terrible gas and I HATED the way it thickened in the water. I tried the Metamucil "cookies" or whatever they're called but they also gave me gas and I didn't find them very appetizing!
I'm taking Acacia now and seem to be doing better with that - at least I'm taking it daily and no gas!
