First off ask your doctor about
getting on Lialda it is Asacol in a 2 pills in the morning dose. Meaning once a day. You will be able to manage your disease beter by not having to remember 12 pills a day through out the day. Second yes I experiance that too. I am not sure if it is normal though. But seeing how you are doing it and have UC too, it might be. I have had the disease for 10 years so what you are discribing happens ocassionally and I would just not worry. Do however always keep a journal of all you do all the time. Which I am sure you have been told to do anyway. Also discuss it with your doctor.
