Just remember that your mind will do things it's probably never done before, thus, some things that will happen cannot be explained - don't stress over these! Just enjoy the experience.
Yes, your mind is going to be working in a whole new way during the experience, and maybe a little different afterward....
Dont be alarmed if strange sensations or feelings happen, because they will... There is no logical reason to taste purple, but instead of trying to figure out why your tasting purple just marvel at the fact that you managed to taste a color.
The thing that seems to seperate those who can truely handle psychs and those who can't seems to be the difference between those who can just let go of everything and embrace the experience for everything it can truley be.... Never try to fight psychedelics, its trying to fight yourself, and in that fight there will never be a real winner. Just go with it and wherever it may take you.... One bit of advice the girl who got me into acid gave me was "Just let the lovin' take hold"... Just go with whatever may happen, try to have fun with it, you will be very much like a small child... Everything seems so new and fasinating... Color stuff, if your into instruments by all means play them.... Some of the best music in history has been written on psychs.
For your first trip, i do reccomend staying away from mirrors, unless your comfortable with your appearance and have no issues with your body and still can maintain "what im seeing is only the effects of this drug, others do not see me as this" you can lose yourself in the looking glass for quite some time if you can handle it.... Mirrors are one of the single most trippy things you will ever witness, your used to looking into a mirror and seeing your own face.... On hallucinogens, what is looking back at you morphs and changes into something far from you... I personally enjoy it, I get lost in it.... I stare at myself, everything but me starts to blur into nothingness, my face contorts, things smooth over, eyes leave and come back, and then i snap myself out of this little trance and just say "what the fuck?"...
Avoid heavy machinery, like cars.... Driving and tripping, not a good idea.... I made a 40 minute drive on 2c-b on molly sunday morning.... I wanted to kiss my driveway when i got home.... I wasn't tripping face or anything, and visuals were down to a tolerable level, it was a dose where i understood traffic laws like stay between the lines... Drive on the correct side of road. Once i was out of the city i knew i would be fine getting home...
