Thank you for answering. Nutmeg is known for being cheap, easily accessible and mostly consumed by teenagers who can't get real drugs. But it's not bad!

Speaking about ways of consuming, I see two options. Hardcore bois just chew it and wash down with water. Less stressful and easy way - just make hot coffee, pour out powdered nutmeg there, stir and drink fast while powder is still floating. It may smell or look threateningly but when you drink it, you'll mostly feel how it slightly burns your mouth and it's metallic flavor.

I didn't feel nausea, I actually felt how it burns my stomach. Well, yeah, it's not healty for your gastrointestinal tract. Spices are not ment to be eaten in that amounts (yet we still manage to xD). Essential oil must reduce side effects at least on GIT.

Yes! Large opened spaces like landscapes were common places I got. Or some surreal empty spaces. Like you standing in the center town square which is expanded to the horizon and there is no single human.

Can't say my body was relaxed, can't anything about what my body felt, because perception of my own body went crazy. It was somehow numb, sometimes it dissolved, sometimes I felt like a statue made of stone.
