I just had the procedure done on Wednesday in Toronto. They did both sides and the battery pack in one operation. I can not believe how good I feel. Maybe I am just very lucky I don't know but, my back spasms are gone and even though my Doctor told me not to I had to cut down on my meds as I was getting over-medded or dyskinesia. I went home Friday morning. The operation was scary but I got through it. I have had a really good attitude about it and I feel that has helped me through this. I have to go to London Ontario to get my transmitters turned on and fined tuned but already I feel very significant reduction in the tremor. I am sooooo happy!!
