Your crystals seem a little oxidized (or plant oils.. harmless but a cleaner extraction will come through experience) I find good breakthrough between 35-50mg.
Also i keep mine in a minifrig, it makes it easier to transplant to a bowl as it has that "soapy" feeling at room temp. Shelf life.... about 2 weeks before i see the slightest oxidization. dmt doesnt come alone naturally, so it seems to bond relatively quickly. even with oxidizing, it still keeps psychoactive effects. Woot woot. id say 2 months would be really pushing it. I never try to keep it around long enough for a whole year lol that's insane!
I'm glad to see people really getting into the businessman's trip, it is truly a WONDER.
you are nervous because you are aware of its intensity. you will always be nervous until you learn to ACCEPT this change. Once i hit it, i clear my mind and dont find that primal urge to fight, after you let go - ultimate euphoria. there is no come up there is no come down. just humming from you perception changing (heart-rate).
Ill bet cleaning your vape is a fucking whore of a job. I found Glass vapor genies to be the most useful and clean.
Not being an ass but I find this tek to give the cleanest and most effective dmt extraction, something to try on your next. if you want less then just lower the materials to you're scale.

great people, intelligent, good conversation but they know their shit and they are very friendly (some that much spice and how cant u be).
im hundreds of trips in now, its my vocation.
ITS ALL ABOUT YOUR FORM OF INGESTION AND YOUR TECHNIQUE!!!
Heres one that a lot of people seem to get.... you hit, it shakes blah blah - kaleidoscopical shapes and new colors. then im in a room, standing, information in forms i can understand are RACING through my head. an overload of thought, to the next and to the next. almost too much to remember! a great breakthrough! as i stand in hyperspace, im talking to a being who is directing me to follow it towards a cabinet. the lower cabinet opens and im hit with information and just as i peak and euphoria... it ends - that last little bit of warmth just exits my body and im back! about 20 minutes as well (i wouldnt had known had i not checked the clock, it is time transcending after all...).
