This is really good advice.
Also, shobs, it'll take longer than 30 minutes for you to come up, most likely. You'll probably feel some effects right away, but it will probably take like two hours before you start tripping out more heavily, possibly longer, but maybe not as long. The onset of LSD isn't as quick as with mushrooms.
