Any Suggestion For Suffering From Menopause Symptoms Which Got Worst With Premarin?

I was just put on Premarin 1.25 because my menopause symptoms have been awful. I ve been on 1 mg and 2 mg of estrace for 8 years. My symptoms have gotten worse over the yrs. I also have taken celexa in the past but did not want to continue on it. I quit taking it over 8 months ago. Symptoms are bad headaches along with feeling very warm and what I call fevered. Which made me feel awful. I would have to take Advil and Tylenol every 3 hrs for approximately 4 days until the symptoms passed which usually came back about 4 to 6 weeks later. I ve had a million tests done and never found nothing. I guess I want to know in the beginning of taking this new med will I feel a little lightheaded and kinda blah. Hot flashes have diminished quite a bit already. I m just wondering if I should take a lesser dose.
