I'm not exactly sure about the kind of lab research that you are doing. Are you doing research where it's essential to sometimes work at 3 AM?
If that's not the case you could have a hard rule of not doing research, browsing the internet or talking to people after 12PM.
It quite easy to put scripts on a computer that automatically shut down the computer at a specific time.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
