Do any of you suffer from this time to time?

What do you do to solve it for future reference?

I'm gonna have to get up in an hour or so, therefore should I now sack that off, get up, go gym this morning and power through the day (Coffee)? Or is it best to get the nap?

There is a lot more worse problems isn't there but I will look and feel like death around lunch.

I will be able to get the lost sleep this evening I think.
