Pre-op - Surgery scheduled for 10/27

Hello everyone! Just a couple more weeks and I'll be on the "losing" side! I'm very excited - not nervous at all. I completely feel this is a blessing. I have been thin - I've been married for 20 years and weighed 135 the day of my wedding. I don't expect to get back to 135, but just want to be "normal" and healthy! So, any good advice for a newbie?!?! Thanks - look forward to hearing from you!
