After 4 or 5 adjustments to increase the pump's output, I was feeling pretty good up. Even my wife noted that I seemed to have more pep in my step. Then, about 2 and a half weeks ago, the effect began to diminish. I went in for another adjustment about a week and a half ago, but it did not help, Even delivering a bolus has little to no effect. I am going back in today to get the pump refilled and have the pump and catheter checked to see if the meds are actually being delivered to where they are supposed to be. I am hoping it's just a matter of a larger dose increase. Other wise, I may have to go back under the knife to have something corrected.
