been on them for nearly two years. i've had painkillers for 15 years due to ankylosing spondylitis and have been through a whole rake of medicine.
about a year ago i started getting tired spells, now in 6 weeks i see the specialist in the endocrinology unit with suspected hypoglycemia. But i reckon it's these patches, i went from 25 to 37 (25+12mg) and i got worse so it seems straight forward and all the blood tests are negative in regards to glucose. As for the constipation, a diet of all bran every morning without fail and it solves that problem. I still take celecoxib and omeprazole as well as 2-6 co-codamol per day. The withdrawal on these patches is awful. I am going to stop them after new year and go back to codeine/paracetamol and the celecoxib(celebrex) to manage the pain.
