When I first started I would legit play for like 7 hours, just because I would get locked in on the grind, or stories so hard I couldnt get off. Nowadays I know what to look for with tags, and usually I start *ahem* jorking off when I know a scene is coming with a character I really like
I try to pace myself and enjoy an update but sometimes I do that and forget completely that I never finished it until the next update comes along and I slowly get behind until I go for option 1 where I play it to enjoy the content then go back on replays to scenes I liked the best.
