Before Christmas, my coffee habit was getting a bit out of control and was affecting my sleep and making me irritable (even more irritable than usual). So since the start of 2014, I've adopted the strict rule of no caffeine after midday, and now limit myself to a cup of tea first thing in the morning when I wake up, and a coffee when I get to work.
So, I've had my morning coffee and... I'M NOW BOUNCING OFF THE FUCKING CEILING!!!!!!
Blimey. It used to take at least four or five cups to get me in this state.
