You can actually use just psyllium husk/powder sans the metamucil (SF or not) - no artificial sweetener, no nothing. I mix a tbsp twice a day with a cup of hot water and some lemon to make it a little (I said little) more palatable

It's a great way to add fiber to your daily menu w/o the carbs

Edited with p.s. - Tanya you can get the husks/powder at just about any health store. Bulk barn in Canada carries it - just ask at the counter.
