Hi, I am no longer on the fentanyl patches
, but did have them for a while. I discontinued them because I never got through the tiredness that they made me feel. Usually the body will adjust, but I was falling asleep all day long.
But...to your question, try different spots on your body, some areas may work better for them sticking on. I found that they would stay on in the area under my collar bone, or on one side of my arm, but not the other.
