Linda F. mentioned a full moon here:

And, this is slightly off course but someone ("CA") recently mentioned that her loved one's neurologist thought that a full moon was an explanation to the loved one's problems. This was said in tongue-in-cheek, and was rather upsetting to CA (as that's all the MD had to offer).
You can do a search of past messages on the term "full moon." Others have mentioned this.
