Before any psychedelic experience I try not to eat much or anything that will disturb my intestines in particular. I try to get lots of sleep. I try not to have done anything that day that I will later criticize harshly.

Before I would make it a special point to abstain from masturbation and sexual intercourse before any psychedelic experience. Now I try to abstain from these most of the time so it's never really much of a concern, and honestly beforehand I did not notice any huge negative effects.

And this is more of a clerical ritual, but I like to get some paper and pens out or anything that I might need during the trip. I do not want to be searching for and deciding on what shirt to change into while on mushrooms for example, as I simply feel silly while engaging in such vanity during a trip (though the fabric on my body does have an immense effect on my setting).

Superstition only does something for you if you believe in it. So overall I take a more physical approach; I don't have any rituals pertaining to "getting lucky" during the experience, but I try to do things that will make my body and mind feel better during the trip itself.
