yeah, but the timing is tricky, I usually dose the tramadol first and in 3 and a half hours min I take the codeine, as codeine inhibits the cyp2d6 enzyme which metabolises tramadol into o-dsmt , I find that the codeine supplements the itchiness and complements the lack of true opioidness of the tramadol, after some weeks tho it becomes really meh since the tolerance begins to rise, especially the tolerance regarding codeine, so it's fun for an occasional treat
