Insomnia kicked my ass again. I got about 3.5 hours of sleep last night. I tried to stay in and get some sleep, but that didn't work out so I'm here at work. I'm exhausted. I have caffeine, but I hate the way it makes me feel when I'm tired (it doesn't seem to do much otherwise). I have this burning and churning in my gut, and I feel twitchy but still slumped over my keyboard. This day can't end soon enough.
