I am currently on Fentanyl patches, 100mcg every 3 days. They are wonderful. They work great, they're easy to apply, and they keep their 'stick' pretty well. The 100's are fairly large but if after 48 hrs or so one side starts to lose it's stick, I apply a large bandaid over it that keeps it anchored down to the skin and that works great.
I've also got Oxycodone for 'breakthrough pain' but haven't needed that in some time, the patch does just fine.
It's normal to develop the narcotic addiction to them and I don't know of anybody who's used them long term and NOT had that. But for me, this is my third round of using them in 3 years and I love them. You just have to know that at some point you'll have to go through the process of getting back off them.
Feel free to holler if you have any more questions about them.
