TAC Engineer of Reddit. How did you survive? (Please share tips, strategies and ways you make it through)

This is open to anyone who works in a TAC (Cisco, Juniper, Dell, Cumulus) I started working in TAC a few weeks ago and I've noticed the job is insanely time consuming. Literally you've got 80 hrs a week of work with less than 40 to complete it, otherwise you're taking it home. Looking for some tips and strategies to work smarter.
