All can have an effect on that, but being on them at the late 30's to mid 40's can be a factor, you know that peri-menopause thing
But while on Celexa, I found them to be lighter, but again it could be my age.
Remeron I was only on for only a month, it zombified me, but that is me, all meds affect everyone different.
But I would check with the sheets that come with your prescription when you pick them up at the pharmacy, or check with your doc, just to assure yourself that any changes are attributed to the med and not any underlying problem, such as hormones, thyroid or age.
I wish you lots of luck with this, and take care, okay?
