I've had this problem for several years and I don't know why, but I'd like to know if anyone else has been through this or has suggestions for dealing with it.

At night, usually starting around eight or nine, I get really restless and uncomfortable. I have a hard time sitting still, writing, reading, or doing anything that requires concentration. This is when I start cleaning obsessively or pacing around my room, and it last a few hours until I get to sleep.

During the day, I'm usually not anxious at all, but I'm like this almost every night, even when things are otherwise very calm and quiet around here. I want to be able to relax enough to work on my writing and music. Any advice would be greatly appreciated!
