"I have used the patch for about five years.  Unfortunately, because of cost and no insurance I had to stop using it.  Unlike the last person, my sex drive was low while using it.  I loved the convenience of it- put it on and forget about it until next week.  The little bit of adhesive residue was not a problem for me.  I too also alternated from one side of the pelvis to the other.  There was a brief period that I experienced a side effect even with alternating.  The area under the patch would become inflamed and would itch.  It might have just been a bad batch of adhesive, because it has never happened since.  I would highly recommend Ortho Evra."
