Hi, I just had my procedure last friday, Jan 23rd. I know each persons road differs especially the time it takes but I think you are on the right road. You know your insurance covers the procedure that is half the battle. The next is to find a decent surgeon. Usually they will help you with the other steps like physical exams, blood work, urine, sonogram... your GP should be prepared to write a detailed letter to your weight struggle and all of the options you have tried under their supervision along with medical issues you have (which is a requirement from your insurance). Know there is support and answers if needed. I also looked on YouTube.com for lapbanders that was another good source of information.
All the best!
