I had mine done in 2 steps, but I've never had a different "feeling" inside.  I can't tell the colon is missing, and I can't tell there's a j-pouch in there......it all feels the same as before.  I had my ileo reversal last Friday, and so far it has all worked very well with no pain, no urgency, and no issues with control.  During the whole process, the ostomy bag was the worst part for me.  I was happy to get rid of it.

The only "different feeling" I had inside was the absence of severe pain once the colon was removed.  It was only after the colectomy that I appreciated the fact that I was living in constant pain and my body had adapted to tolerating it.

I mean when you are having a bowel movement is it different to having a "coloned" bowel movement? With this end ileostomy of mine I realise that my small intestine gets active for an hour or so as it removes the waste. I can empty my bag once it's full , I have that luxury without feeling any discomfort. Can I do the same thing with my pouch?

Yea, that's different......you no longer have a rectum full of dehydrated and compacted stool that you push out as turds.  You have a pouch that's about 2/3rds the size of a rectum, and it's full of liquid, or a thick-ish liquid.  I've just been relaxing and letting it run out.  A little push after that yields a poot or two and maybe a tad more liquid and that's it.  This happens every 4-6 hrs for me right now, hopefully I can extend that time out some more over time, but pooping 6x/day with no pain and no medications is so much better than pooping 12x/day with pain and expensive medications.
