Hi, I have left a mass of dried magic truffles for 6 months in a side-room, exposed to some indirect daily sunlight. How long does it take for it to lose its potency? Also, the truffles I bought were claimed to be of the Hollandia variety, but others online claim this is a fraud- please explain.... Lastly, I have found an online dosage calculator, with the hollandia category missing(I read that one should put in tampanensis sclerotia instead). What should I do if I make a mistake and find I have overdosed? All I read was that one should drink something very sugary(like freshly squeezed orange juice?). Any other tips? Would gulping lots of water and then vomiting heavily into the toilet within an hour of consumption work? Cheers.
