I went to the chiropractor today. Thank you, Charlie. He said my hip was slightly out of socket. He said he knew this because one leg was longer than the other. Then he popped my neck a lot. I've been trying to sit up straight the rest of the day. I had a nap attack for 3 1/2 hours afterward. I haven't been sleeping as well as I'm used to, lately, so I hope this helps.
