I was on methadone for a year and now I am on
suboxone. I had a lot of terrible side effects from
methadone. Weight gain, terrible damage on my teeth, ect... and I have only been on suboxone for about 4 months. My docor tells me that if you wean down slow enough, there should be little to no withdrawals. I haven't experienced it myself yet. But I know for me, suboxone saved my life. There are no miracle cures for addiction, everything has side effects. My opinion is that suboxone is safer.
