#2 Sit up

If you’re going to be working on something that does not involve a lot of physical activity like studying for a test or working on your laptop, don’t get too comfortable. A big soft couch or comfy chair is not the place you want to be if you intend to stay awake. Sit at your desk or at the kitchen table and make sure you sit up nice and straight. The more comfortable you are, the harder it will be to stay awake.
