UPDATE TO MY SURGERY
I have a laparoscopic ileostomy after 6 years of severe UC. The doctor said I'm 100% healthy now that they removed the colon. I think they were right :) My life has never been this good. I hate the bag, but my life is so good now it's hard to hate.
In the last week, I went a little crazy. As soon as I got the green light from my surgeon (6 weeks in) to go back to "normal," I did everything I could to push myself (within reason).
I know it's different how we all respond to fitness/food/drink/etc., but maybe my experience can give some hope.
Food: I'm an idiot and barely chew my food, but it all comes out somehow? Even had a few scares where I swallowed larger pieces than planned, and everything comes out as paste.
Drinks: Whether it's sugary, carbonated, whatever... no issues.
Alcohol: This week I had wine, hard liquor, beer (draft and can) and nothing caused any changes. In fact, I actually slept through the night without gas for the first time. I was really drunk too; Bahah
Exercise: Also got the green light to work out. Did a few days this week and pushed myself at about half the level I normally would (was a bodybuilder before surgery). All good ;)
I hope this can give some hope to other noobs like me. I know I tried to find topics like this when I started out, so I hope it's helpful.
