I left. She went to sleep in the afternoon and slept soundly four hours; awoke and ate her supper; went to sleep again and slept soundly all night.

I came home from dining out and did some surfing on the internet and suddenly felt quite sleepy at around 10:30 PM. I went to bed at about 11:00 PM and slept for 4 hours. I woke up and was unable to get back to sleep until about 5:30 – 6:00 AM. I thought it was the melatonin causing my problem. Even after taking 5 mg of the melatonin I was unable to get back to sleep. I now wonder if it works at all.
