I did the patches for the first month after surgery. The only complaint I have is that they didn't seem to stay on throughout the day like they should... like the adhesive wasn't strong enough so they would roll up by the end of the day. Not sure how much I got out of them, so I went ahead and switched to the vitamin chews for now until I am a little further out. Anyone have tips or suggestions on why they wouldn't stay on?? The directions said to put on parts of your body with little to no hair, so I would wear on my shoulders.
