I started to track my symptoms into my agenda about a year ago or more.
When I was able to see the consistancy of how I felt vs what part of my cycle I was in, I was able to *Chalk it allup to* having another hormone episode. The scary ones seem to last a week or so but when I can look back and see that I have been through it before, it ables me to calm down and weather the storm.
The only draw back to charting it all is if anyone ever gets ahold of my agenda LOL!!!! They'd think I was nuts

I'm 47 this year and have been at it for about 3 years now with the fatigue, am I dying, brain fog stuff.
It really helps to keep track
