I ve bee on on method one for two year , 80mg a day. I wasn t feeling good so I took a half of a 8mg suboxone , and now I m really sick throwing up , cold sweats. How long will I be feeling sick? ... I get my next dose of methodone tomorrow morning, will I be feeling better after I take it? ..... I will never do this again , i thought it would make me feel better but here i am feeling so horrible..
