Thanks. Unfortunately I don't know anyone in the States, I'll see if I can get some from India like Yujin.
Interestingly, Pentasa didn't work for me at first either. I was diagnosed here, but I started comparing notes with some people at ColitisUK (being English) and discovered that the average person was being given a dose of Pentasa two or three times what I was getting in Japan. (Some people were on 1500mg with each meal) I raised this with the Japanese doctor, and he agreed. The law in Japan is very strict on dosage, and he's legally not allowed to supply a large dose. I managed to get him up to 750mg with each meal (I'd been to a festival, and upped my dose in an attempt not to poo everywhere~
) and this seemed to work.
