"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."
