Didn't know there's a "car sickness" strictly related to reading the phone while in transit, I knew there's those people that can barely survive riding a car but that was it.

I do get the "reading phone motion sickness" a couple of days after heavy drinking. The hangover has worn off but there's this weird after-effect which gradually fades over a few days until it completely disappears. At first I thought how the hell do I get car sickness until eventually correlated with reading the phone and having to stop or else.

Based on my manifestations being chemically-induced, wonder if that's also valid in general. Some level of Gaba or something, which is normally lower in most people, gets elevated by drinking and then (hopefully) cleared.
