I understand where you are coming from, but I cant, or choose not to just kick, after having several experinces of quitting runs on o-dt cold turkey. I'm too much of a baby to go through the AH cold turkey that can last a whole month. Its not an attractive prospect.
Ive been trying for months to taper down, with no success. I've psyched myself out of just kicking. But as i believe Bupe will help me quit i think it will. There's a very large psychological aspect to how to manage coming off opis IMHO.
I'm now feeling ok, after taking all 4 quarters of the pill, and a phenergan (been feeling sick all day, phenergan has worked and cured that) one pregabalin and a couple of etizolams to supplement. I was starting to feel bad a couple of hours ago and i've not been able to eat more than a few morsels of bread, but apart from a headache I feel OK now. A hundred times better than just kicking IMO.
I waited about 30 hours after last taking AH, and had read that the switch over is not so brutal if you take tiny amounts of bupe to start with.
