Hi Shadders,
I'm 42, and finished my rads this time last year. I'm ER+, and went on tamoxifen, but also Zoladex for 6 months, before having my ovaries removed earlier this year. The Zoladex injections shut your ovaries down completely, and my Onc wanted to see how I felt, before a more permanent solution.
I've been very lucky with SE's so far, I just find it more difficult to regulate my temperature than I did pre-menopause! For me, the worst of the hot flushes disappeared within about six months. There are many women on here who have been prescribed mild antidepressants to help with SE's though- to greater or lesser success. I can't remember which thread it was, and I still can't navigate round this new site, but it was fairly recent. I also found a 'Chillow' very helpful at night,
Best of luck x
