Well, you will not be productive. But sometimes, a few additional unproductive hours can be helpful.
In addition to what people have already stated, try to have music playing in the background. Ideally, it should be energetic classical music - it doesn't have distinct rhythm, but won't bore you. But use your musical tastes as a judgment. If there is some music that helps you do mental work, use it.
Also, shaking up your body is good. Physical exercise is obvious. I've used to take regular showers through the night. They do not have to be extremely cold or hot, the feeling of water on the skin is enough to break the sleepy state for a while. Keep the bright lights on. Dim ones can make you sleepy.
Hope this helps.
