I share the same sentiment. Grabbed a laptop last week to be able to wfh somewhere else and entertain myself too, and to try if I couldn’t get gaming to work on Linux, and had that feeling of curiosity back about what is new and how everything works. The feeling was lost sometime after Windows 7, and replaced with a slight feeling of dread about where everything got misplaced in this newest shiniest iteration of Windows.
Couldn’t be happier with fiddling with distros!
Walking will help sort your guts out as well, so by going for a late walk, you can take the problem to the outside!
Otherwise it’s probably just a question of your gut biome having a lot of gas producing parts.
