Thanks for your reply. I have already tried prunes, prune juice and aloe vera. Unfortunately, I can't say that they have helped much, if at all!
So far the only thing that helps me has been the metamucil + miralax combo. Even with this combo, I still have constipation symptoms, but they are much more manageable. No straining, difficulty or pain during movements, which was a major problem before.
On a different note, I've noticed over the past three months that if I drink even the slightest amount of coffee, I get severe gas and stomach pain almost instantly. The same with certain red wines. Is this related to IBS? I find these symptoms odd because up until three months ago, I could drink several cups of coffee or wine with no symptoms whatsoever. I thought maybe I had an ulcer or gastritis, but the doctor said the gastroscopy showed nothing in the stomach region.
