Sorry, but are you fucking stupid? You want to trip during school? Get Real. Mushrooms are not pot. In fact, since you have only used pot and alcohol, they are nothing like you have ever experienced in your entire life. Psychedelics aren't some kind of weak-ass pep-pill or relaxant something you can take and still do your every day activities... RESPECT THE POWER OF ALL PSYCHEDELICS AND ALWAYS USE RESPONSIBLY AND WITH FULL KNOWLEDGE OF WHAT THE EFFECTS WILL BE!!! Shrooms aren't a drug that you take because "Ohhhh maaaannn, I just got some SHROOMS... hahahaha I'm Gonna get FUCKED UP.... YEAHHH!" You think you know what being fucked up is? (because of your experience with ONLY pot and acohol) I know you don't. Fucked up would be tripping classroom. You have no idea what a bad trip is like and if you trip at school, I GAURANTEE that you will have a bad trip. No questions asked. But whatever, you're not gonna listen to this, and you might get your shrooms and eat them before school. In fact, I don't care what you do, I'm just trying to give you some advice that you desparately need to hear.
Get fucked. Come back here. Tell us how "AWESOME" it was.
Or.... if you want to do it the right way you'll do at least a minimal amount of research on the subject. I'm not trying to scare you away from shrooms here. I think shrooms are glorious, but I also respect what they do to me, and for that reason I don't put myself in unnessesarily dangerous situations.
