Anyone here had a revision

Hello Everyone, I would like to introduce myself.  I am a transplant to SC from NC.  I had the mini-gastric bypass 7 1/2 years ago.  I am scheduled for a revision to a RNY next month.  My first surgery worked great for me the first 3 years and then I unfortunately failed it or it failed me.  Which ever way you want to view it.  I am very nervous about this surgery.  Mostly nervous about not having long term results and ending back up on an emotional roller coaster.  I read the revision forum alot so I do know that people can regain their weight back.  I was wondering if there is anyone in the SC forum having a revision or had one and would love to hear your experience.
