Good luck hun I bet you love the results.
I had mines done like 2 and a half years ago with the hospital group aswell. It's definitely good motivation to loose weight thats for sure!
Also a tip - after the op you will probably find you are a couple of pounds heavier (10 in my case

) but don't worry it drops off really quickly I think it's just because your body is swollen and because of the anaesthetic! Eat healthy food afterwards no matter how rubbish you feel - I made the mistake of eating takeaways constantly because I couldn't cook and I felt so sore!
good luck!
