Before I had my trial - I too was very worried about the buzzing feeling...and if that would be better or worse than the pain. BUT after my permanent implant, and self-programming, I have found just the right amplitude and frequency - that now I actually LOVE how it feels. For me it is this nice, gentle massaging feeling, and I too have gotten to the point where most of the time I forget that it is on

As for the jolts...I have a thoracic unit, so can't comment directly on the neck moving issue, but I can tell you that there is MUCH less jolting with the permanent, due to both better securing of the leads, AND eventually scarring in of the leads. When my unit was first implanted I had to change programs every time I changed position. Now, I rarely change the program at all, as the leads are no longer super sensitive to my norma movements.
