Well that sounds like some good progress! So it took about
five days for the blood to disappear... sounds about
right. Just have patience; you'll continue improving slowly but surely. As long as things are moving in the right direction, that means you're doing the right thing, so just keep doing what you're doing!
If you get to the point where all your symptoms are gone, I'd stay on the enemas for at least a couple weeks to a month after that to make sure things are in remission before you start "weaning" yourself off them... dropping down to every other day for a couple weeks, then every three days, then once a week, etc. Some people continue with once a week just as maintenance, but I never did. Or if you like the peace of mind, you can just stay on the nightly enemas indefinitely. Everyone responds differently, so it's up to you.
Either way, glad to hear about
the progress. Hope it keeps up for you and gets you into remission.
