Hi Jaedon,
Sorry you're having some trouble with the pentasa. How long have you been taking it? I had some trouble with upset stomach when I first started taking it in 2009, but it went away after a couple weeks, and I've been fine ever since.
I take 8 capsules a day, but not as recommended.

My GI originally had me taking it 3 times a day (3 morning / 2 midday / 3 evening) -- but I always forgot to take the middle dose. I asked him if it was OK to go to 4 and 4 -- he said to give it a try, but if my symptoms increased, to go back to 3/2/3.
I've been fine with 4 and 4 -- I take 4 in the morning after breakfast, and then 4 before I go to bed.
But to be fair -- this is totally NOT how it is recommended, so please discuss with your GI before trying anything new with your dosing schedule!
