My husband went a few nights without sleeping much and started to have delusions. He even called the police to come out because people were trying to get in the house. None of which were true.

Lack of sleep can have dramatic effects on me. I'm bipolar so the last time I was hypomanic I wasn't sleeping. I was getting terribly grouchy and had all kinds of stuff going on at one time. My doctor makes sure to check on my sleeping patterns and monitor it. And gives me medicine to make sure I get my sleep.
