Yeah I remember sitting in a school lab watching memes for the first time and just laughing so much and for so long, but everytime after the laughing was just a little bit less, that first peak never happened again. I'm much older than you, currently I'm resisting with my own children the pull of having their devices nonstop until they can learn self control, but it's so difficult to explain why I am so mean and won't let them game endlessly. Occasionally I do give in and they experience the numbness I think.

I'm not up to a dumb phone, I try to just set restraints for myself with phone use, but it's really hard.
