How can I wake up?

[divadee]

I have the most boring job, the toddler is not sleeping well, i don't drink coffee and I am literally falling asleep at my desk. What can I do to wake myself up? I have put the fan on to make it cooler and have a breeze on my face, I have gone for a walk around the building, I have zero work to take my mind off falling asleep.

A fruit smoothie often perks me up.
Go for another walk and get one. Ice cold if you can.

Am Apple and a spell running your wrists under a freezing cold tap.

I used to work in TV and they had plenty of less solvent ways of waking up or staying awake but I wouldn’t advise those methods
