WOW, from 70mg to 0 in four weeks! I was on 100mg for about a year and I detoxed at a rate of 5mg's a week. at the end all I felt as far as withdraws were lack of sleep, I got about 2 hour a night without sleep aids, and diarhea. this lasted about a week. I dont want to give you the wrong mind set but I will say this, Methadone clinics dont want you to detox. Mine talked me out of it twice. I was a good paying customer! well..good luck!
