Hi Shelly, what a bummer!! Perhaps your surgeon can deal with the issue . . . I bet your are frustrated. I was doing fine until yesterday evening, I got the dry heaves - it was pretty awful. My surgeon said it can happen, I didn't do anything to cause it that I can see but my stomach is super tender now.
As far as signs go, this morning I felt so bad that I wished I had seen a sign to stop me pre op - but now I'm feeling better . . . it isn't easy though, at least not what I thought going in. I go back to work tomorrow, hope I wake up ready to go!!
I'm sorry you are running into these blocks, maybe the timing will be better when things fall into place - it's hard to just let things happen the way they do, for me at least!! Keep your chin up, it'll happen and in the long run a few weeks won't make any difference since with the band it's a slow journey. I'll keep pulling for you!!
