I went to Monterrey Mexico for my fill,and My Doctor was awesome! Both him and his wife(also a Dr.) were so much more understanding and willing to talk and ease my fears. The hospital I went to was owned by an American and boy was it a better experience than any American hospital I have ever been to! I t was a great experience,I think it is just up to your circumstances.
I was just banded on the 21 of June. I was not ready for the pain of the gas pressure, it was worse than the surgery! But I know it will be worth it. Good luck!
