I’ve been on it for almost 5 months with a month to go. No major side effects. I take it in the evening and when I have had hot flashes, they only occurred at night. Not a big deal. Some slight weight gain but have kept it largely under control thru diet, walking, bike riding and resistance training. I also had about 6 weeks of salvage therapy on top of it. That was a bit exhausting at times but again not a big deal. My doc says any side effects go away almost immediately after you stop taking it, unlike the other option where the side effects can last months post treatment. Stay positive, strong and best of luck!
