I started taking Metamucil in July and WOW has it made a difference! At the time I was spiraling into an all out flare and within 2 weeks I was feeling so much better.
The last time I tried taking Citrucel I had a lot of gas but this time around I started with a small dose of Metamucil and then over the course of 1-2 weeks I got up to a full dose. And like I said, it took 2 weeks to really make a difference so stick with it.
Also - I did some research at the time and found a chart that said that Metamucil was the only supplement that absorbed both liquid in stools which I definitely need.
