Hi angie246, I used Elleste Duet Conti for just over three months (in between trying out other forms of HRT) and found that not only didn't it help much with post menopausal symptoms (the hot flushes, incontinence, dry stinging eyes and dry mouth and blocked nose, and very painful joints all continued to a greater or lesser degree), but that it had some dire side effects as well, such as you've found - sore breasts (which usually goes away after time, I have to say), increased pulse rate and tinnitus, and increased vertigo (I already had vertigo but some forms of HRT made it worse).
At one point I switched to taking it at night and that seemed to help, a little.
It's worth considering switching to another type, especially as you've given it a fair go of six months.
Good luck xxx
