So much good advice and sharing here, there's not a whole lot more I can add on top of what's already been said. My experience with detoxing, at least what I remember most, was run-on anxiety attacks and loss of sleep for weeks.
What I'd like to mention is that I had no clue that detox or treatment was an option available to me. I just assumed that I'd have to sweat it out at home and hope I survived without any complications, and that's exactly what I did. When I talked to a few doctors after a couple months sober they asked me what made me do something so stupid, going cold turkey after daily use since 1980. Looking back, I wish I would've known better or had the common sense to do it differently, but God protected me as he'd been doing for years.
If you're thinking about achieving sobriety, please consult a doctor and be honest about your disease. I definitely didn't use the brains God gave me when I approached sobriety, there is an easier and softer way.
