When I'm stuck in a situation where I'm really tired, usually on a 72 hour binge of lack of sleep or something I load up on caffeine pills, meaning lik hydroxcut hardcore, or t3 or some other crazy shit and I do something active for a about 15 minutes. Be it a really really hard run, or pushups til I puke, or just jump rope. The pushups usually make me feel the best and I'm not ridiculously sweaty, but its guaranteed to keep me up another 4 hours or so.
But be aware this might cause you to be uncomfortable because your heart will feel like its going to explode.
