I don't know if it's weather, or planetary electromagnetics, or what. But it seems like I just can't keep from feeling sleepy, the past few days. Yesterday, I could barely wake up, it seems, and sat down to read and fell asleep for an hour. I wasn't the only one, either. Today, I just feel like I don't have enough oxygen, and keep yawning. I can't focus, this afternoon. I've also felt semi dizzy. Even lots of coffee doesn't help. Some sort of low-grade bug? Toxic chemicals in the air? Strange weather?
