We have eat truffles 4 days in a row (we stareted in Sunday) and I almost didn't eat them before. Just 2 times. First time I eated half portion with my brother and it didn't work. Second time I eated some home made shit.
We have go for a Delphins Delights. We eeated 5 grams per day (in one eating), 3 days in a row, I was pumpin up, euforic first two days, like to interact with the people. Third it day it wasn't work (just a little bit), I think cause we have go out of the crowd. Fourth day we eated High Hawaians 10 grams in one eating and it wasn't work (just a little bit) for 3 hours while we have be out of the mass. After we have came in the centre we start to trip big time. W couldn't find the hostel while we have be in street next to. Alot of dimensions and colours. Unoftunaely I got sick for 2 hours. Maybe cause I almost didn't eat that day and I eated alot night before with alot of soya sauce which made me my stomach crazy and I still feel little pain in the stomach. After that 2 hours it work just a little bit and it was very good feeling.
The day after we were on road back home and completely normal, while yesterday I had flashbacks like today, too.
On the other side friend was nervous about people on the Dolphins Delight. First day he eated 10 grams (the others days just like me) and he tripped he is soaring/levitating, he is sweating.
All in all we are back in Amsterdam in spring, or maybe earler who knows
IMPORTANT: I drunk beer while I was "on" and that stimulated alot. If I didn't drink I wouldn't have that feeling, no way. I am talking about Dolphins Delight from Kokopelli.
