For reasons unknown, I've been having a hard time sleeping at night. It's frustrating for me to lie in bed wide awake while at the same time feeling so tired. On Wednesday night I'd had enough so I got out of bed at 11:30 ish and took a sleeping pill. Thinking I had plenty of time for it to wear off I took the full pill, rather than half.
Thursday morning dawned bright and sunny and I swear I could barely open my eyes. I moved at half the speed I normally do and it took until roughly 10:30 am for that pill to wear off. Lesson learned and last night I tried the iPod approach instead with better results.
