For the past 6 months I've spent at least 6 hours a day napping or laying in bed. When I'm up all I do is think about going back to bed. I saw my pnp today and she thinks it might be related to the dulling effect of long term haldol use along with worsening depression. I've never heard of excessive sleeping as a side effect of haldol other than when initially starting. Just wondering if anyone else has experienced this.
