I think the most sensible way would be to try to find someone in the US who is trying to get a replication study going. That way, not only would you benefit (or not!) but the entire ME/CFS community would gain knowledge (and in future no patients would have to go this way alone like you have to now).
The usual suspects for such a study would be Nancy Klimas, Daniel Peterson and Lucinda Bateman or their respective institutions to name only few. Or maybe Derek Enlander in the NYC area. Anyway, get a doctor knowledgable in ME/CFS (not necessary one of the names mentioned) who has at least contact to these people.
Furthermore if you want (or have to) do this as a last resort without the help of ME/CFS doctor and outside of a study, make at least sure you have an oncologist who is properly knowledged in the drug, its risks and side-effects.
