My first shroom trip was 1.7 grams, it was fantastic. I didn't eat the whole day, which was a really good idea. They didn't take that long to hit me, about 15 or 20 minutes. I had visuals right away, along with a good body high and some color effects. It was pretty intense for the first 1hr and 45 mins for me, after that I mellowed out and tripped in my friend's room for 2 hours just looking at his decoravite walls and whatnot.
