The fill is interesting. LOL! The nurse has to jab it into the port and mine kept missing! It is kind of surreal getting stabbed repeatedly but it didnt hurt that bad. Just like getting a shot really. They do this in front of an x-ray machine and that s kinda neat. they make you drink barium (again) to make sure the adjustment is good. Im not sore at all and I have know judgment on the after affects because i am on liquids right now. love, peace, and Gary Sinese!
