Thank you two for the post. I am very interested in this pump. I am on the whole list of painkillers, methadone, vicadin, neurontin etc. The pills cost close to a thousand a month. I have yet to have a surgery, and am very nervous about it. Being on so many pills and building up tolerance, i am not sure how I will deal with the pain of an operation. If there are anymore people that have had this pump, please take a second and tell us more. Thank you. LD
