Sounds like you are set for success, Pete.
What you described sounds like a Roux-N-Y (or RNY, in WLS - speak) That's what I had...and there are a lot of us here. The only other option I knew about was the lap-band (my first consideration) but the RNY is the best for me. There are others where you don't "dump" and since sweets are a BIG problem for me, I need that deterrent to keep from eating them.
You will be amazed at what you learn over the next weeks that you didn't get in your pre-surgery learning experience. I thought I was prepared - NOT!
But that is why this place is so cool - one or the other of the people here has been through whatever you are going through...just ask and we will give you advice - and tell you to go to the doctor, if that's what it takes. We aren't doctors..we are peers...
