Wake up, and then wish you hadn't. Resolve never to drink to excess again. Try to block out the sunlight and go back to sleep. Wake up a few hours later, go downstairs and attempt to talk to housemates. Fail, and retreat back to bed. Try to remember why a second bottle of wine seemed like a good idea last night. Drink a cup of tea brought to you by your lovely housemate. Eventually feel human enough to go downstairs again in search of sustenance.
Drag a pot out of the cupboard, noticing that it seems heaver than normal, and put it on the hob. Slice a pepper carefully, being aware your physical coordination is not what it usually is. Fry it in oil with a sprinkling of chilli flakes for a few minutes. Add a couple of handfuls of red lentils and enough water to cover them by about 5cms. Retire to moan quietly on the sofa while they cook for 15 minutes or so, adding more water if it dries up. When the lentils are soft and the whole mixture looks thick and soupy it's ready. Add some salt if you want.
Eat from a bowl on your lap. This is not a time for tables and chairs. Feel much better, so go back for seconds.
