My GP was always at me to stop HRT...grrrr. At one point maybe 5 years ago, I forget now, she persuaded me to try anti-depressants instead, but it did nothing for me. I eventually stopped and went back on HRT, low dose (25 mdg estradot patches).
Good luck with finding something that works. I guess it's good to trial coming off HRT every now and then. My tedious story of such a trial I won't reprise here...suffice to say, headed back to GP to get a new HRT script next week. Sigh! I am 60. At this point, I feel like this sh*t will never end. (She says, testily, after another night of drenching sweat and v. little sleep, whine whine)
