A little worried?
I'm sure it's totally from quitting smoking (WTG, BTW) and you should get over it by the time you have surgery on Tuesday. For me I was in the ER 2-weeks before surgery with dehydration and they said as long as I felt ok and it was not respiratory I was ok. And I'd say you will be too. But if you still feel this way Tuesday AM just mention it to them.
Good luck on Tuesday!!!
