I've hurt your feelings, and I'm sorry. We spoil our two dogs horribly too. But your post was kind of like hearing "I take my child's pain medication because I'm an addict, but it's okay because I spoil them rotten, and I think that they can stand the pain anyway". You see the craziness, right?
I agree with the poster on suboxone, you'll end up on the stuff forever, and its crazy expensive. I've heard that withdrawal from both suboxone and methadone is very hard, possibly worse than opiate withdrawal. I'd go over to Bluelight.com (a website for addicts) and check out the posts from the people who have experience with opiate withdrawal. I've heard that there are OTC meds that will get you through the worst of it. You may not be symptom free, but it will help. I wish you only good luck.
