Hi Laurarose,
I was on Letrozole ( aromatase inhibitor ) until my recent illness and is now on hold til we work out treatment for my Congestive Heart Failure due to side effects from the Adriamycin chemotherapy. I did not have hot flashes with menopause just some insomnia, but the Letrozole had me flashing day and night. I did try some OTC vitamins to try and help with the flashes, but no results.. I hope you feel better. I see the Oncologist in a few weeks and really so want to get back on the Letrozole...
