Then I have a few more questions. My sister-in-law has one of these and she has had her's for several years (just got her first 7 year battery replaced). My first question is; is it true that the doctor takes you off all pain meds before the trial? or before the implant? If so I have been on my pain meds for the last 5 years straight and I am really worried about withdrawls. How do I control this?

Secondly; I understand that you are awake for the trial. But are you awake for the actual implant? If so how painful is this to handle? and how long is the surgery?

Third; I am only expecting a 30 to 40% decrease to my pain is this a viable expectation?
