I am not (taking the silica). It didn't seem to be helping - and I noticed more gas than usual. I wasn't sure if the silica was to blame - but I eliminated it and the extra gas went away. I must have been sensitive to it somehow. Gas is one of those things that has been an issue of mine. It's the first symptom of my IBS to come back. I'm stable and not having problems otherwise. I go by the diet (other than the occasional cheat), take my fiber, probiotic & enzymes... and I am a pretty happy girl. There are some things I just have to avoid (dairy).
