We are all different. You say to avoid all raw fruits and vegetables. I eat raw fruits and veggies every day in my protein fruit smoothies. No problems with them at all.
There are pouchers who can eat fresh fruit and veggies without pureeing them like I do.
You have figured out what you can and can not eat and drink plus how much psyllium you need. In the beginning it felt like I couldn't eat anything! I used a lot of psyllium and Imodium and gradually dropped using them. I use Imodium and sometime psyllium capsules when I get c-diff and/or cuffitis. In other words when I start making too many loo trips. I use Imodium when I have to be away from facilities too long.
My pain no longer has nothing to do with what I eat, I have figured that out in 26 months.
