You have a very mild version of this, you'll be fairly close to ok.

I am talking about those who are currently roughly 21 and under, who have been raised by an iPad or Surface or some kind of smartphone, who literally become highly agitated or go into hysterics the way I do when its been 8 or 12 or 16 hrs with 0 nicotine.

Go look, you can find compilation videos of actual children, toddlers, babies, who just throw a temper tantrum untill their magic entertainment rectangle is returned to them.

Obviously not all younger people are like this, but a disturbing amount of them are.

I wish there were studies on precisely how serious and pervasive this is but uh... you know, Trump kind of defunded basically all scientific grants, purged government databases of existing 'DEI' science, bullied universities into submission, and the government is currently on hiatus for all purposes other than terrorizing people.

Blame parents, blame society, blame capitalism, sure, yes, whatever, point is that I am legitimately concerned that as the entire economy enshittifies, as we go into the Second Great Depression, lack of access to these things will even further intensify basically psychotic behavior amongst a fairly large subset of the population.

EDIT:

Tinnitus?

Maybe look into active noise cancelling head phones, or download some pink noise tracks wnd play that at low to moderate volume on normal headphones.

Those should still work without an active net connection.
