YES... It DOES make a huge difference... and NO, it is not just a bunch of talk.
When I worked for two Denver hospitals, the ERs always put on a staff and a half...for the day/night of the full moon and the following night...
If the Full Moon can pull the mighty ocean waves...it certainly has no trouble moving our mind-bodies which is mostly water.
Not to be alarmed...just don't take yourself too seriously and practice 'letting go' and knowing 'this too shall pass.' In some cases, people seem to 'perk up' and actually feel BETTER.
Anyway, just a heads up to everyone... as for me, I'm just going to hibernate and watch a good movie!
