I would robotrip at like 10pm when my parents went to bed, and I'd be coming down around 2:00 a.m. when the same Futurama episodes were on again and it was like watching whole new episodes
As for interesting philosophical reading material, I quite enjoyed: the Nag Hammadi library; The Kybalion; and anything about morphogenetic resonance.
If those topics aren't interesting to you, any music is good, and any normal movie is recommended, since you'll see it from quite a different viewpoint.
Heads up to those new to DXM: do a small test dose (~90mg) before jumping into a larger one, since you might have an enzyme issue that makes the experience overly intense and possibly dangerous. Take only DXM-containing products. Consult the plateaus chart online to see where you're at. Always research things beforehand~
