JayGuitar,
Is it helping you at all?
While I was flaring, I was using it 3 x per day, after each meal.
Now in remission, I'm just using it once a day, after dinner.
As far as I know, there's no problem in using it as long as you need it.
There are people who stay on the mesalamines for years and years, so IMO, yes you could do the same with slippery elm.
One other question: are you using L-Glutamine powder as well? It's important in colonic repair.
How are you doing?
