Just a quick question.. I'm a bit worried about how long my spice will keep for, I store it in total darkness at room temperature. But how long will it retain its potency for, any idea? It's already 4 months old and I appears to be losing its potency :-/ ie can't seem to get breakthrough from it lately. Or is this some sort of resistance to the effects of it that I've developed now, rather than the spice spoiling?
