The truth is (for me at least) that when you are a bit hung over, that is the perfect time for lucid dreams. During the morning hours when your sleep is a little bit disturbed by an upset stomach or something it is easy to enter at WILD. In other words, it makes it easy to enter a dream through the hypnagogic stage (which is the most interesting). When you wake up from a not-so-good sleep, make sure your intent is set on staying alert while falling asleep. You will become lucid. By this I don't recommend drinking in order to have a lucid dream. But yeah...
