The expression "sleep off" means to sleep or rest in order to recover from something, such as a hangover or illness. In other words, if you have a headache from drinking too much alcohol the night before, you can "sleep it off" by taking a nap, so you feel better when you wake up. Similarly, if you have a cold or flu, you can "sleep it off" by taking plenty of rest to help your body recover.
