I'm 10 months in. At about 4-5 months I started experiencing changes to my depth perception and sense of perspective. The best way I can describe it is an enhanced sense of space, of dimensionality. It's still happening (or different), but I don't notice it so much anymore as I've become accustomed. It's subtle and hard to really tell if it's visual or perceptual or both. I also "feel" my surroundings more, which I attribute to reduced dissociation also.
I'm still a superb parallel parker!
Reine, there's irritation and there's OH MY GOD, CATACLYSMIC, RUN FOR THE HILLS UNENDING SYSTEMIC IRRITATION (along with its best friends titanic anger and reactivity)! The first may not be hormonal, but the second sure was for me!
