Start with a low dose. Around 1 gram. Get a feel for it a time or two. Then step it up as you feel comfortable possibly up another gram. They will make you explore your mind and self. Don't do them if you have been in a negative or bad mood as it intensifies how your feeling usually. Don't do them in a bad unsafe environment. Lockup phone and keys. Have a sober companion with you the entire time you can entirely trust. Relax. Plan to do nothing in public.

What OhVenus_Baby said has good info that I would agree with. I would also add that it comes it waves. You'll feel the effects intensely and then it will ease up a bit. Write down things (ideas, past trauma, reasons for your behavior) that you would like to think on. I would say think about it really hard before hand and try not to think about it the day of the trip. Your subconscious will be already on it.

Think about mood and setting. Some music without lyrics was good for me. I ended up listening to some orchestra covers of Tool. Lofi beats were good too. I also found some video of a POV walking on the beach and watching the waves.

Also draw and doodle with your paper. It looked cool to make the lines. Some people will tell you to stay inside, at least for your first experience. I went out my first time on shrooms and it was great. I walked in the grass and found a pine cone. Your experience may very. If you feel weird about tripping that day then skip it till you do. Let the universe tell you when it feels right.

As far as the rewiring or after effects....it may take a day or 2 to fully fill changes cementing. You'll have a lot of thoughts. That's why doodling helps me represent my feeling or thoughts on a subject.

The rewire part is like just giving you a different perspective. You might always smoke a cigarette after lunch. That is your normal routine. You don't even think about it. After you eat you last bite, you hands automatically move to the smokes and you move to the door. You are following this path because it is so routine that there is comfort in it. Even if you want to stop. Your body craves the familiar routine. After tripping, it's like your mind shakes an etch-a-sketch and erases the lines. Or it was tire paths in snow and now shrooms cause a new snow to fall and you don't know the old path.

Trips give some people perspective so they can close old painful wounds. After we learn from events, it's good to close the chapter so we don't get dragged down by it. Many people can't see that there is another path, you just got to make it. Again not everyone. Just me and many others experience.

In the moment It was mostly concerned with the task at hand, which was usually drawing, listening to music and adoring the funky visual effects (no halicunations tho). But the most specific thing that came out of it was changed relationship with some of my friends.

One of them was, for instance, quite annoying. I seem to be quite sensitive to the stuff, meaning that I was the first one "in" and the last one "out". He was the kind of guy to tease people a s a joke. It annoyed me before, but during the trips I finally realized how immature and annoying that stuff became. He was joking about me while I was in a vulnerable state and expected maturity from the people around me. The changed perspective meant that I finally got to look from the outside in and determine that I maybe should disengage from the relationship a bit.

It's not that I wouldn't recommend others to do it. I just won't do it again because I now realize how much this kind of stuff kan really affect you. As long as you're in the right headspace it can be a very cool experience. I still remember, after hours of chill music, how we all suddenly fell silent after an intense build-up followed by a heavy DnB drop. It felt physical, like I was suddenly pushed into the couch by the bass and couldn't get out. Not sure if I'll ever experience music in that way again.
