GoingTo MakeIt is correct it can be mild or severe, from my own personal experience during my detox from methadone, it was bad during the first two weeks, but I still functioned, as best as I could anyway, I tapered down from 90mgs down to 2mgs then stopped, my symtoms were like many who stop methadone
, no energy, depression
, bad anxiety, couldnt sleep, sneezing, etc. It has been 2 1/2 months since being off methadone & I am back to my pre-methadone days, & very happy about my success!!!
