When I was on methadone for pain issues, I started tapering at 50mgs a day and got down to 30 in two months....no problem. So....that was ten mgs a month before I went to detox. They brought me down with the Sao juice in three weeks to nothing....and I kicked like an epileptic mule.
If 30-35 doesn't cover the H, don't go above 50. Ten mgs a month is fast but I didn't feel it. So...maybe 5-7 mgs per month and then slower under 20. I never had the chance to hit the notorious wall but it was coming at the rate I was tapering.
The peeps at the detox said I was going fast; they started me on a 30mg equivalent of Sao but added more two days after I got there.
