Have my Surgery Date Set March 8

Just found out my surgery has been scheduled! It seems like the battle I have been fighting for 30 years is going to be won! I have gone back and forth of going down the surgery route for over a year, trying everything to lose, but never successful. I started this process in November 2016 and it's been full steam ahead. My biggest challenge will be having my pre-op testing done on the 27th, 2 days after returning from a cruise. I am guessing I will need to be good to ensure I don't gain weight. I am so ready for this life changing journey to start and am ready to join the losers bench!!
