The folks there might be able to help you. That group is not well liked here, but that has to do with "politics" more than whether people there can answer your particular question. (Leaders of CHSG tend to fight against the alternative treatments -- "busting" -- discussed here, which is not appreciated.) The group I was suggesting is just called "Cluster Headaches." The top, pinned post at that group is about 5-MEO-DALT.
