When you say you have used the enema for over 19 years, I don't supose you mean daily for the whole period ?? What is the longest period you have used them for ?
Also for those who have a problem retaining them, this may be of interest. I was prescribed the ememas 21 years ago when I was first diagnosed with UC and as much as I tried, I could never retain them. I was given the supository form instead. Now 2 years ago, it got so bad that I decided to try the enemas again. I cannot give you the reason why, but I have no problem at all retaining them now, but I only use them at bedtime. This would be the only positive difference I have noticed while aging tho.....lol
