I am not sure exactly how long,but I have not had any noticeable symptoms at least 6 yrs. I was supposed to get a scope every 2 yrs. but my PCP was refusing to give me a referral.(I am on medical assistance because I am disabled,so maybe she was saving the gov't $$) Anyway, I ended up with two skin diseases that can be related to having UC.(erythema nodosum and pyoderma gangrenosum) One of the first things the dermatologist said was,you need to get a colonoscopy,it has been too long.(normally if you have UC and you flare up with EN/PG, the UC gets worse)
fast forward....The prep was not bad at all.It is newer and called "Moviprep". It is no where near the amount of liquid you drink with the other prep.It also tastes A LOT better.When comparing the two,I would never complain about Moviprep.LOL.It is really sweet and tastes like strong lemonade. You drink 32 oz.(in 4 sections) one night(with a glass of water following) and then another 32 oz. the next morning. NOT BAD AT ALL!
Anyway...the good news is I am in remission.No active UC at all.
