If you get good enough at playing guitar, especially acoustic, you can literally buzz. It's only really apparent when you stop that you can feel that buzz fade away.

Sex, masturbation, or finishing a hard workout/hike and relaxing with an ice cold soda.

Food coma

Negative ions

Teaching: That moment when someone's eyes light up and their whole facial expression changes from confusion to understanding. I love the challenge of figuring out how to reach that with each person.

Dancing or working out to my favorite songs: It feels like my body is taken over by the music, and I can keep going endlessly while everything else fades away.

Probably just picking up a cat and hugging, and when your cat just rubs against you.

And also flying drones and imagine you are a bird soaring through the sky.

FPV would be best, but even just those normal drones where you use for photography is still fun to just zoom around your neighborhood.

I once flew like 4km from a nearby park. I also once forgot about the tailwind then stuggle to fight against the find to fly back so I lost the drone because it eventually ran out of battery, felt like I trying to land a passenger plane that's running out of fuel lol

Listening to music, especially while drawing and getting to reflect on how much got done in-between every song. It's one of the rare times we feel focused, even if only for minutes at a time. - Tabitha (ey/it)

High ?

Reaching the cloud-base with a paraglider, especially in weak-days where you really need to fight to stay in the hair and fight for every meter of altitude

The "zoomies" I get post-run

Reading. Writing.

When I finish doing a lot of chores or one big one!

finally beating a really tricky level/boss in a video game (but not so tough that by the time you beat it you're just over it)

Scoring a goal or winning a close sports game.

Rollercoasters.

When the code finally works, the computer issues are fixed, the kitchen is cleaned.

Shikantaza meditation So smooth

A good ride on a bike or scooter

Night time stream high

I mean, what constitutes a drug is kind of hazy, but I'd say damiana. It's a herb from the arid south of the U.S., and is brewed into non-alcoholic tonics, teas, and it's also a pleasant smoke. Great alternative to both cannabis and tobacco, and it's a solid tea.

The flowers are also cute.
