I do this to myself all the time. Like Pip and Ustwo said, set your alarm and get up. It takes about 3 days to form a bad habit and the same again to rectify it. So if you do this for 3 or 4 days, you should start to feel back to normal and pretty good.
I find that when I get there, I usually feel so good I start the cycle again.. *sigh* but I can verify it has worked for me repeatedly
