Here's the advice, see diet below.
Prior to this diet, what worked best for me was one Rowasa enema at bedtime. Hold it overnight. Lay on your left side as you sleep. Hold 1/2 bottle if that's all you can at first. You have to be a fighter and hold this medicine overnight. This is where the battle can be won.
I have experienced a very good stretch of time with extremely reduced symptoms after suffering with it for going on 7 years. In the past I have tried many different things including Asacol, Rowasa, Prednisone and others. I also have tried various diets in the past with varying levels of success.
What has worked for me extremely well for the past 2 months is a diet change. I significantly reduced the amount of sugar intake and, in particular, avoid anything with high fructose corn syrup. I also am avoiding milk. Absolutely positively NO POP!!! And, absolutely NO FRUIT JUICE or HONEY!!
It is somewhat difficult, but give it a week and see if things get any better. I know it is tough. This means no pop, no fruit juice, cookies, cake, ice cream, or just about anything sweet. No milk, no coffee, no tea. For my sweet craving, my wife has been making me plain fruit pies w/o sugar.
The up side of it is that I have been able to eat just about any regular meal.
Snack on pretzels, saltines, fruit. Avoid potato chips and junkie snacks like cheez-its. Some of these contain fructose.
Read labels, give it one week. Stay on your medication while you do it.
My symptoms shut off like a faucet. I hope yours do too.
