Opiates are hell to detox from - I can totally relate. Was addicted to Vicodin for almost a year after a serious back injury, and it was the worst year of my life. Almost died from combining Vicodin with alcohol, and the detox was even worse. Nowadays, I'd rather deal with the lingering pain than rely on painkillers again. Nothing good came from it.
Bless your heart and I wish you much success. Very glad you recognized your problem and are taking steps to correct it. You have much support here from people who have been where you've been. *hugs*
