HI Kim,
So sorry to hear that Stan is still having pain problems.
I don't have any experience with the patches Stans using, but I used to use a patch when I tried to quit smoking. I noticed that where I placed the patch made a difference to my nicotine withdrawals.
If I put the patch on a skinny bit of me it worked fine.
If I placed the patch on a bit of me that had some meat it did not work as well, perhaps the absorbtion is affected by what it has to pass though. I know this sounds odd, but it really did seem to make a difference.
Hope you are taking some time for you, and that you and Stan are able to do a few good things together.
God bless you both
Cee
