I also have started Lialda, and it is much easier to take pills just once a day. I think they are working, but am also on entocort and will begin tapering off that next month.
Why do you forego your medicine? Why on earth would you want to have diarrhea?? It seems like you would be in a continuous cycle of adjusting back to the normal dose.
Lialda is better tolerated than some of the other drugs for this disease, it doesn't break down until it reaches the colon and you only have to take it once a day. Maybe you should ask your doctor about it, if you're interested in changing meds.
