I have seen posts about soma and even one that goes into modafinil as a possible potentiation. The thing is, I would like to lengthen the duration of Soma?s effects, but I don?t want to interfere with the conversion of soma into meprobate. I generally take Tagamet with my Valium and Suboxone but I?m afraid that it will interfere with that conversion. I can?t find anything that addresses both topics.
