Thanks so much for your help. I've decided in this instance to soldier through the day in the hope that I collapse at around midnight. I'm tired as fuck right now and it's only coming up to 7.00! So I'll see if I can manage it.
That's hardly a long term solution though so I'll definitely take on board the more realistic and practical advice offered here once the initial panic of starting teaching is out of the way.
Sincerely, thanks to you all for your advice.
Evidently a career teaching fine art hasn't equipped me with those basic life skills that would've told me cocoa is a stimulant!
