I had discomfort for a week after surgery, but it was irritating not debilitating. The doc activates for me on 8 August. He said I should never deactivate, but he will show me how nonetheless. I did receive a wallet card with instructions and the QR codes for the device, as well as a med alert bracelet. I am hoping for a huge change from the 40+ ounces I am now leaking per day.
