Life can definitely feel easier after you find a job with a steady workflow. It's the slow creep of responsibilities that will eventually overtake the stress of having been a student.

Oh the people who managed a few critical but rarely used pieces of equipment left? Looks like you'll have to figure out how to run it yourself now with limited notes. Your project is floundering because other departments aren't being upfront about their workload? Now you'll have to babysit their work and send constant emails asking them to do their job so you won't fall behind schedule. Are you a doc approver? Better take your laptop with you during vacation to be available for signing off on it.
