Hey @LisaO, I too was diagnosed 51, premenopausal and put onto Tamoxifen, I've been on it for 14 months, saw my oncologist yesterday. Had blood tests to see if its kicked me fully into menopause and if it has I might be being changed to an AI because I've had two bouts of vessels bursting in my eyes and they don't know if its the Tamoxifen. So off to the opthalmologist and then decision will be made on 5/10. So thing is nothing is written in stone, each person is an individual and their treatment plans are tailored to their needs. So I actually wouldn't be asking I'd be telling as you will still be on medication and a couple of weeks is really nothing in the big scheme. GO FOR IT!!! And have an absolutely sensational time. Wooohooooooooo - I think I'll have a swim by proxy ;-). Have fun xoxo
