Jabberwocky
Frumious Bandersnatch
a small dose of 25-50mg of either should suffice. just dont make the mistake of dosing too much of promethazine because it will cause you to go through a delerious state for a short while. some people (who probably aren't the full quid in the first place) actually find it enjoyable but it's far from it. if you wanna trip out use a conventional drug like LSD or DMT etc.
