Sorry, I pressed send too soon! :-/
I was referred in Dec '11 and the dietician appointment wasn't until July '12. My consultant appointment was scheduled for December, but was cancelled by the hospital so that wasn't until February '13, then the camera in March '13.
I wanted the sleeve, the consultant I saw said a mini bypass had been recommended because of acid reflux. I don't have this (which puzzled us both!) but he did say it was a quicker operation, so whether that means cheaper too I'm not sure. Anyway, I can't stand the thought of being re-plumbed, so it's the sleeve for me, which Mr Small said was perfectly fine.
Good luck and don't worry about the timescale, it will fly over! Xx
