what was I thinking!?

Ill be 2 weeks post op as of next monday. Im also on full liquids until next monday, then I can move to soft foods. Canned chicken is on the list for soft food and ive been anticipating eating it so much that I decided for lunch id try it out. I dont know what I was thinking. I was trying to justify it by saying not everybody even does full liquids after surgery for 2 weeks. On top of that I had a little parmesan garlic sauce with it. Idk if it was the chicken the sauce or both, but I screwed up. Now im nauseated and belching like crazy and a little dizzy. Ugh other than making myself sick could I have damage or hurt myself?

No, you didn't hurt yourself.  Your body was giving you a warning not to rush things.  The different food phases are to help your pouch heal.
