Hello All! I currently have a band and am considering a revision to a sleeve. I have had the band for 4 years. I am still yo-yo'ing depending on my fill levels. I just want something that works without the constant adjustments on a monthly basis. I am not sure if my insurance will pay for the revision although I do have WLS coverage. My BMI is 41 today....I am just worried that the sleeve may not work for me either.
