I think if you just spend time reading this forum you will get most of your questions answered. If not just ask.
Most of the things you have asked are here already so take some time and start reading.
Most of us were banded in Mexico by Dr. Ariel Ortiz at the Obesity Control Center, the sponsor of this forum. There are numerous raves about this man and the clinic he operates so again I suggest to just read, read, read!
I am from Portland, OR and there are alot of us OrEgonians here on the forum. I am not so sure about how many in eastern oregon though. I am happy to chat with you anytime if you want to PM me. I was banded 6/4/06 and had my 1st fill 1 week ago so I am still fairly new at this.
I have absolutely no regrets and look forward to coming to this forum EVERYDAY as my support system. It's great here!
Congratulations on taking the first steps to a new you!! Yes you too can do this.
