bigjim6278 0 Posted January 10, 2015 I have been vended for over 10 years and was doing quite well with 9 cc in a 13 cc band having lost 90 lbs but suddenly felt no restriction band had lost all but 1cc. Had not had a fill in 4 years. Has anyone heard of putting in heavier viscosity Fluid to prevent leakage? Share this post Link to post Share on other sites
