HI....JUST GOT MY FIRST FILL, LAST WEEK...HUM ...ONLY 26 DAYS AFTER MY SURGERY...IT WAS TRUELY THE WEIRDEST SENSATION I THINK I HAVE EVER FELT. iT DOES NOT HURT AT ALL. MY DOC INSERTED THE NEEDLE, AND FILLED ME UP, THEN HE HAD ME SIT UP ON THE TABLE, AND AS I SIPPED WATER, AND FELT IT PASS THE BAND, HE WITHDREW FLUID. JUST TINY AMOUNTS AT A TIME. THIS CONTINUED UNTIL WE BOTH FELT THAT I HAD ENOUGH RESTRICTION. WHEN HE WAS DONE HE PULLED THE NEEDLE OUT, IT WAS A REALLY WEIRD FEELING, BUT NOT AT ALL PAINFULL. HOPE THIS HELPS! GOOD LUCK!
