It is not that we have not tried a higher dose, it just simply did not work. I made the decision to not go any higher and to lower the dose to see if there was any difference which there is not. The only thing that has happened since I started taking this medication is the bowel program has changed and is not as effective.

Was mainly just interested in knowing if anyone had ever stopped it cold turkey with any problems. If not I may just be the first one to try it out.
Thanks for all the information on the other medications.
