No, when I lived in the NL I did shrooms and I was actually quieter than usual. Everyone trips differently, though. A friend of mine would always insist on wearing his heavy coat while he tripped. He would also wander like crazy, so we always ended up following him around. Sometimes he took us on the most fascinating adventures! Oh and by the way, I am surprised that the tripper wants to eat anything. Everyone I know who has tripped never has interest in food while tripping.
