You need sleep. Get more sleep somehow. My 45 mile RT commute is unbearable without sleep.
Personally, I would not ride the day after my second job, if I had one.
I use 3m reflective tape found at auto part stores for $4 a yard.
Do not put it on your rim since your brakes will take issue with that. You can always purchase tires with reflective sidewalls.
I have my tape on the back of my rack, both of my fenders, my fork, crosstube, and cranks. I'm sure there area few more places I can put it if I try.
