Pred taper question

I was put on pred on 11/2 for a flare up (20 mg a day) because nothing else was touching some inflammation in the last 8 cm with instructions to start tapering after 2 week if I was feeling better. I called my doctor today, but of course he is out of town this week so I just spoke to the nurse who reiterated my instructions. That being said, I am light years better, going only once or twice a day from 3 bms and 3 episodes of just bloody mucus with no stool. I had no bleeding over the weekend at all, but did have a little bit on the end of my stool today with my only bm. So, does this qualify as better and I should start tapering? I asked if better meant symptom free or just improvement and the nurse felt improvement was what he was going for. I do still have some white mucus in my stool, but I know that this is part of the healing process.
I suppose I could give it a go and alternate 15 and 20 a day for a couple of days to see how I feel, but the taper always terrifies me! Thanks for your advice!
I am also on 4 shire generic lialda a day and 1 colocort enema at night. I plan to keep this in place.

It is a really low dose but I am super sensitive to pred so we try to keep it as low as possible. I can't sleep right now at all, so I would be more than happy to come off of it, but I also don't want to feel like garbage over the holidays! It worked really quickly, within 4 days I was feeling like a normal person again. There is nothing I hate more than vague instructions...

I would try alternating for this week only and then drop to 15 next week if you don't see increase in blood.
I do have a question about the white mucous. I have had a bit of white mucous and I also have left side pain (my disease is on left side). I wasn't sure what the white stuff was at first and was wondering if it was mucous. I only have one BM per day now too and no blood. A few weeks ago I was having diarrhea and saw some stringy mucous and thought I might be flaring but then it calmed down. I am sorry to hijack your thread but I never noticed the mucous before because I used to use the Rowasa and I thought the white stuff was from the enemas. Do I need to be concerned?

Don;t worry about mucous. As mucous is our very, very least concerning symptom. Our IBS friends have a lot of mucus within their stool, and by definition they cannot have inflammation. Yes it can be white/off-white globs by themselves or embedded in stool, stringy white stuff, etc.
