Welcome dear! Thanks for consulting me at my virtual clinic. I have worked through your case thoroughly, and I can easily realize your health worries. Being your physician, I reassure you not to worry as things will settle down very soon. Covaryx has less side effects than premarin. Premarin causes weight changes, covaryx don t. But covaryx has got androgen in it. I think that s why your physician changed to estrogen only pill i.e premarin. If your main concern is weight gain then shift to covaryx again. But if your main concern is loss of libido, stick to that you are taking right now. I suggest you to start jogging and your goal is 5000steps to jogg or walk daily and make a record of it. Get a pedometer for the recordings easier. Use healthy foods and fresh fruits and plenty of fluids. Meditation will help too.  You may follow up with a direct question by going to my profile, so that we may manage your problem in a better way.
