I know this has been discussed before and I don't know how to explain this real good......but I am on day 4 of a cold and this morning I woke up feeling more calm than I have been in a really long time. I noticed last night also that I went to bed with a very calm feeling that is very unusual for me. It's as if there were some change like day and night happening in a good way to my brain. This may be a total fluke but I wonder if it has anything to do with certain chemicals released as a result of my cold? I know in the past sometimes I have felt better physically when I have a cold but this time my mental is noticeably different? I have not taken any cold medicines or done anything different that I can think of. Just curious if anyone has experienced this. I guess I will find out soon if this feeling lasts.
