PMS symptoms - am I a werewolf?

Hi all,
I start my period today and upon waking up, feel like a fog has been lifted. 
We all know this veil that lifts and all of a sudden:
We’re not crazy;
We aren’t weak and wimpery;
We aren’t mean without reason;
We aren’t emotional monsters that sprout hair from every follicle,* who’s drool drips from our blood-soaked fangs;
WE’RE HORMONAL!
I don’t get the chick that’s been living in my body, she’s like the PTSD victim version of me and my thoughts.
I’m either being lightly drugged once a month or it’s hormones. (It’s hormones) BUT is it normal? Anyone seen a doc and have an answer?
Does anyone else experience a personality shift that goes way beyond a little grumpy, complete with fuzzy memory? 
Answers that come from love will be received with gratitude.
