I've worked in tech since 2008 and only for 2 of those years have I had to be "on call" past 6pm. ymmv.
Giving a very generous 1 hour for every meal and daily 1-hour workout, that still gets you 12.5 hours of non-working screen time for your work week, and 7.5 hours of lower-stimulation entertainment. And then you have your weekends for weekend stuff. What does your schedule look like where this is a serious problem?
Being constantly socially online with people you don't live with is honestly overrated. Cutting out social media is a good first step, and strengthened my most important social connections, and completely eliminated ones that I hadn't realized were empty and meaningless (do you really need to be "friends" with everybody you knew from high school?)
