OK so I've got these 100mcg fentanyl patches and I want to get off, but I'm not sure how to go about it. I have read that the generic ones, without the gel, can only get you off if you chew or suck on them. I'm used to like 60-80 mg ,at least,of hydrocodone at a time, how much of this stuff do I chew? Just freaked out about OD on a friggin patch! Also, I heard you can use a heating pad, but how long does that take to kick in and how long do I apply heat? Help!
