Sleep deprivation - tips for work?

[SleepDeprivedCabbageBrain]

My baby is going through a hellish regression and I'm having to work on just a few hours sleep. (Unfortunately I have to, as really need the money).

I feel hideous to be honest. I'm crawling along at a snail's pace, making loads of mistakes.

Any tips for surviving this and staying employed??

When I have to work on a few hours sleep, any combo of these help a bit:

Cool shower before work
Fresh air
Coffee
Berocca
Make up to look more awake esp undereye concealer
Citrusy perfume
Quick meditation if you can fit it in!!
PMA

Good luck!
