You and I are really close in surgery dates! I just got the news yesterday that mine is scheduled for the afternoon of the 15th. I've been having anxiety on and off since I started doing pre-op appointments, and I had a dream last night about surgery.
The scariest thing to me is the possible complications, but it helps knowing that most occur in 1 in 300 to 1 in 500 patients (which is what my surgeon told me). I think it's the initial phases I'm most worried about, but I'm excited because in the long term I know this is what i need to do to get healthy. As long as you follow your post op instructions you should be okay, but never hesitate to call the surgeon or someone in their office if you think something is off.
Also, I've been cranky being on my pre-op diet as well. Sometimes I handle it well, but around certain people I don't hold it in as well as I'd like. I think it's because your body is already experiencing change, and not at a rate it's easy to adjust to.
