It is generally agreed here that you need to be off triptans and other blocking medications for five days before a bust. I say that is "generally agreed here" because some dissenting views have been expressed lately, saying that while triptans might block busting, there is no need to be off them for five days. I don't think anyone can say what is "true" about that, so many of us still recommend the five-day "detox." It is said here that you could use a triptan right after busting and it won't "unbust" you, but you'd have to wait five full days after taking it. As with Denny, it's my understanding that the D3 regimen and busting are compatible. You've probably answered this somewhere already, but what meds are you taking (for CH and anything else, since some non-CH meds are also believed to block busting)?
