Thanks, it is honest and partially useful.

There's no non-chemical boost that I can think of that will match the chemical boost.

Music is an obvious counter-example to it. People who like it, can get completely "crazy" from something like Faithless : Salva Mea or The Prodigy: Firestarter. It is the strongest non-drug drug I know.

Parachuting, bungee jumping and motorcylce riding also count. I just don't want to do them. But they do work like that.

Meditation is a funny topic. First of all, 99% of the people I know think it means sitting with an empty mind etc. and you should expect some mental effect. However, what I practiced for years was entirely different, in the "red hat" tradition of Tibet it was not about empty minds but using imagination to visualize and also saying mantras, and it was not promised to have any immediate "trippy" effect, and indeed it didn't. The idea was more like long-term improvement. I should also say that in these gompas people tried to sit up straight but did not work very well.

At another time I visited a Zen center, and here they made me use a very tall, thick pillow and sitting strictly on the edge of it, which was not so in the other one. This kind of moved my lower hip forward, upper hip back, creating a position where the bottom of the spine could be balanced, and it was easy to balance the upper spine, creating a much more straighter spine position than before. And it was the more common mediatation, just empty mind and watching the breath go out. And this kind instantly had very, very, very trippy effects.

However I read stories from people who do not care that much about position, just sit up in bed roughly straight and still have effects.
