You might think you're weird because you have trouble falling asleep, but insomnia is way too common. To know how to fix it, you have to know what's causing the problem. And to understand the problem, we need to learn something about sleep itself.
You already knew about caffeine, but who knew that bacon and eggs for a late super could interfere with sleep? taking time to wind down is a problem for me. When it's already the wee hours of the morning when I finish work, and I know I'll be back up at five, who wants to take time to wind down? That's because I don't have trouble falling asleep; I just having trouble finding time for sleep. -via Laughing Squid
