A a festival several years ago I had been drinking all day, it was about 6 in the morning when I got back to my tent, didnt think think about using the toilet before bed, popped a valium and went to sleep, woke up in the morning thinking it had rained the night before and the tent leaked. unfortunatley it was the second night of 5 so had to sleep in a pissy tent for 3 more nights. learnt my lesson i can tell you.
