5-20g should make you trip but be careful in large dosages its make you really sick and even send you to the hospital i think.
Two handfulls of nutmeg powder is enough to kill you, but if you dont die, youll hallucinate, or so they say.
I once did 80g of nutmeg... first it was amazing very very euphoric. When I layd down i could feel my body bending and the surface I was laying on was waving. Music was kinda wavy too. The trip lasted whole day. I took the nutmeg 6am and it was still fully on 11pm. But next morning I was basically dead when i tried to stand up from bed I just could not stand, I had no balance what so ever. And body temperature was low and breathing very slow and deep(so my friend told me. He thought that I was goanna die any minute). When I was lying on the bed I occationally passed out and skipped time(close your eyes for a sec and when you open them few hours have passed).
