@kmakm yes yes to magnesium. Tablet form an hour before bed. Got a footbath? Epsom salts in that too. Magnesium spray on belly.
...also agree with that too.
What time are you taking other meds? At the young womens' support group I go to, those ladies who have been on Tamoxifen and other hormone inhibitors say taking it at 830pm is best. This is following the research that our bodies process most of our hormones between 9-11pm, a little like our brains process abd clear out waste materials while we sleep.
On this front, your mind is pretty dirty at the moment Kate! (Sorry couldn't miss that opportunity)
