I know what you mean. I refused Rowasa for 9 months, because I was nervous about
it and didn't like the thought of it. It freaked me out. Then, I got desperate enough to try them. They're not that bad. It's a small amount of fluid and it is possible to retain them at least for a short amount of time. I used them for a week (even though the GI told me to do 2 weeks). It helped! (I'm not better, but it definately helped.)
You see, the problem with oral meds is that they may not disintigrate in the correct spot and the suppositories only effect the rectum. The enemas can go all the way through the rectum and get to the trouble spots.
My new, awesome GI told me that even if you put it in for a short time, there will still be some benefit.
It's hard, but try to get over your hesitations.
