I did notice when a rain front is approaching after nerve heightening Santa Ana winds,
I get more somnolent then usual. With less help.
My wife was similarly effected by the weather.
When we visited Eureka where there is different weather in ten minutes of ten miles,
we never felt the variances of mood from the weather. I liked it. Too wet for her.
Sleepy weather so nice when it happens and one can exploit it.
