Does this mean I'm tired?
I tend to feel sleepy when im tried so i guess that makes two of us
How do I stop myself from sleeping, when I want to do the work?




No but really, hit up the caffeine or something.
Exercise also actually gives you more energy. If you're sitting around all day, for extended periods of time, your stamina and energy can take a dive off a cliff. Just go for a walk around the park or something. Concentrating too hard for too long will burn you out. Take a walk for that as well.
Try to have as many lights on as you can, they'll keep you up. Natural sunlight is probably the best.
Get some ventilation or a fan going too if you can.
If its the computer thats stopping you from studying, i suggest turn it off or go to your local library, unless you absolutely need it. Install leechblock for firefox (theres a chrome equiv too) to limit how much time you spend on timewasting sites.
I also just realised im procrastinating on my physiology exam by writing this, oh the irony.
I've tried not going on facebook or reddit for the entire day to see if that helps, but i tend to find something else unproductive to do.
This was me in VCE. I had to turn off my screen to get work done. Soon, that wasn't enough. I had to disconnect the keyboard or the mouse. Wasn't enough. After that i had to unplug the mouse and keyboard and hide them around the house. Then i had to hide the powerboard...screen..etc.
I stored it in a room of the house we never used so i wouldn't be tempted to touch it.
Here's what happened when i did that:

(Hint: It's a mouse.)
Try disconnect it as much as you can though. Change the password to your steam account, facebook, etc.
