Thank you...silver & Greg,

I appreciate your responses. Silver, I think you may have some good ideas about how the chemicals are distributed. I am about 5 lbs under the specified weight & so far, haven't experienced anything unusual.

Greg, it is interesting to hear about your side effects. I was surprised to hear about what you have experienced. My pain specialist has told me that "addiction" is when I need more of the med because I am misusing it for the feeling I get from it. He explained the other possibility is building up
"tolerance". This is when your body needs more of the med in order to control the pain. After over a year at this level (I had been on 100ug for 5 years prior which never worked) neither condition has occured...guess I'm lucky. They take blood anualy to check liver & kidney functions. I am surprised they don't check weight, but am thankful they don't. There is no plan on my going off the fentynal unless this dose stops working. At that time, I will worry about coming off of it. At that time I will also have to find something else that will work & that is never fun either

Thanks,
Debbie
