As adult I no longer find it very interesting, & intensive training (with chess problems, etc) always results in weird nonsense chess dreams and in distracted daydreaming about difficult positions. It's like my brain inefficiently routes game problems through my visual cortex.
Stimulants: Caffeine makes me better to a point. Modafinil (which I use off and on) makes me markedly worse and tends to land me in time trouble.
