I didn't sleep last night (or much over the weekend with one thing and another) and am now absolutely shattered and working on a reception desk.
Someone just came in and I've just discovered I've reached the point where I actually can't talk in coherent sentences - my words are slurring into one and I'm becoming completely incomprehensible.
It've also got another hour and a half to work. This could go quite badly.
Has anyone got any good ideas of how to wake oneself up?
