HAVE ANYONE HAD SURGERY IN MEXICO, OR KNOW OF ANYONE

There's several..oodles.  In fact, there is a wls mexico board out here.  You should get lots of responses there as well. For the DS procedure, the only surgeon you want to trust to that is Dr. Gilberto Ungson. For any other procedure, get many, MANY references.  There are some not-so-reputable surgeons that have people on boards like this 'fishing' for new customers.  The more real references you can get, the better.  Look for long-time posters with lots in their profiles.
