I've been on the fentanyl patch for a period of time. It does work very well. I recently switch to hydromorph contin (long lasting morphine) and it didn't help as much as the patch, so I went back to the patch. So, it does really work. Let's just say you'll know if you forgot to change it on the 3rd day.

uch: That's the biggest challenge with my brain fog. It's better than popping pain meds every 3 hours like I was doing before.
What dose are you on? If it is much higher than what you are used to taking you may be groggy a bit before you get used to it.
Also, never put it on your chest near your heart. I did once and I thought I was dying. That was one very scary night. Luckily I soon figured out it was the patch before we called an ambulance.
I think you will be happy with it. Just write down which day you put the new patch on. In the hospital, they marked it right on the patch. Not a bad idea!
Good luck.
