So I, like everyone else, is slightly unnerved about what the vomiting means. All I tried to do a little research on where the author could be eluding to. Here's what I uncovered: [Sisyphus, condemned to eternally roll a boulder uphill only to have it roll back down, represents the futility of a pointless task, a feeling akin to the existential nausea described in Sartre's novel. Camus's "The Myth of Sisyphus" uses this myth to explore the human struggle to find meaning in a meaningless world, which echoes the feeling of nausea that arises from a sense of the absurd.] So if the author was drawing inspiration from this, it could be that he actually doesn't remember his past life and it's just his body reacting to the situation in the way he would have a his previous self, as he would have likely considered the kissing a pointless task therefore causing the nausea/vomiting. Maybe it's a big stretch, but I'd take just about anything over him tricking our precious teacher.
