An interesting book can put me in a similar situations to drug addiction. My wife had to put her foot down on my reading issues, and now I avoid books unless necessary. People are always confused when I explain it to them.
Omg finally another person! Sometimes I just can’t stop reading and I’ll stay up all night reading. During some specific sequences when I am reading a new book I experience euphoria. At one point I needed to stop myself from buying more books because it can get expensive when you are buying a new book every couple of days. One thing that helped, at least with the money issue, was discovering free web serials. Few are literary masterpieces, but there is enough to read that I can get my fix.
If you're reading to the exclusion of all other things that's unhealthy but the idea you stopped reading is equally unhealthy. It would be better to continue reading with boundaries than to give up the betterment that reading brings.
