yesterday i had my first psychadelic experience and it was amazing. i had ate an 1/8th (peanut butter and shroom sandwhich) while watching across the universe. i really attribute my great trip to the movie as the end put me in a great mood. i had great visuals, thoughts, body high, etc and it overall was some of the most fun i've ever had. if i were to do shrooms again, should i expect that my trip will go as good as this one or was it just my first trip because ive heard peoples first trips are often their best ones.
It's all about set and setting. Sounds like you got it right your first time. Any trip after your first can be just as good or even better as long as you have the proper set and setting. And yeah, you should expect it will be good, because that will increase the chance that it will be.
