So I've been on semi solid food a few days now. All is going good except some times when I eat something crazy happens. Today I took two bites of tuna- I can only describe it as an almost having to burp pain in my mud section it gets more painful before it gets better- I get really mucusy in my mouth and I vomited from this feeling for the first time today after about 15 mins the feeling passes

Hey tt...sounds like you may not be ready for that tuna yet. When food is too dense/dry apparently it's painful and can actually give you a "stuck" feeling, followed by your body's response of secreting more saliva/mucous in an attempt to get it "unstuck".....not speaking from experience, I'm still on full liquids after my surgery, only from what I've read here on the boards.

You might be eating to quickly or bites are too large. Even if you think your eating slow and small bites this may mean you have to go even slower than that and also smaller.

The sliming is your systems prep to vomit. SLOWER & SMALLER

or.. You just may not tolerate tuna for now.. give it time

If it is just tuna then it just may mean that you need to back off a while. I had the same problem with eggs right after surgery. But now after 3 months its fine. Not everything is going to go down easy right away, but check back on it a month or so out, and you should be cool. Just remember you got to chew. That was one thing that I thought would be easy, but you really have to remember to do it every time.
