Make tea!! I used to just straight up eat them all the time and have to suffer through the nausea. Last week I made tea with a group of friends and come up was fast with almost no nausea.
Just use a cup of water for each person: First grind up the shrooms, then mix with boiling water in a cup. Let steep for 10 min, strain, drink. Keep the wet shrooms and steep a second time to make sure you get all of the psilocybin.
Works like a charm
Almost too well... one of my friends was in a confusion and ended up breaking his phone in half and had to get a new one after the trip lol
