I put the patch (Mylan Fentanyl, 25mcg) on yesterday after work as you guys suggested. I was really surprised by how small and thin it is.
I thought I would wake up this morning in no pain, but no such luck. However, I only had to take the one Oxy in the morning and another one tonight. And I actually cleaned my kitchen and did two loads of laundry! Do you know how long it's been since I was able to do that much in one day?
And no nausea, dizzyness or any other side effects.
The real test will come on Monday when I sit over a microscope for hours at work. We'll see how I do.
I did scratch the thing half off already though by mistake.

Luckily, I have some of that tape in the house that they use in the hospital to keep your IV attached to your hand, so I put a piece of that over it. I might just use that each time for a while until I get used to not scratching in the area where the patch is.
Thanks again for all of your advice!
