I found extremely quickly that playing a string instrument (improv) with Ketamine is just incredible. I tried other instruments -- doesn't compare. I am also thinking of trying an real organ but the logistics are not simple... But I cannot keep doing this for more than 30min - 2hr normally.

What do you do for longer experiences?

Think a lot on the come up. I love dancing and listening to music. Meditation if it fits the vibe. Pretty much anything that help the visuals flow. Music videos and video games are amazing. I would recommend VR on one of your trips it's pretty intense.
