Fatigue is real and it sneaks up on you. Don’t be afraid to pull off the road and close your eyes for 20 minutes. You don’t even have to sleep, just resting for a few minutes is super helpful.
Similarly, use your car’s automatic features when possible if they reduce fatigue. In your case, that probably means using cruise control. I’ve found that if I don’t have to actively manage my speed, I get less tired.
Assuming you’re in a tight hand drive country: Keep right except to pass!
At least in my case, my DOC IS 3.0 modem was having connectivity issues. My neighbor in another apartment had similar issues: dropped connections, slower than expected speeds, etc. Switching to DOCSIS 3.0 modems solved the problem. I guess Comcast upgraded their hardware and it wasn’t compatible with my modem anymore
