I was on the Climara patch (.05) for 5 weeks and it didn't help the flashes or other symptoms..but at least it didn't make things worse. My doc just ordered bioidenticals and had me remove the patch. After the 1st dose, I had such a bad headache, I took 2 more doses and more of a miserable nauseous headache. The pills were Bi-est (1.25) & Progesterone ( 100mg). My recent saliva tests were all in the normal range, although I've had no menses since January and I have a multitude of symptoms...flashes, fatigue, brain fog, burning feet, etc. What do you think happened when my new body reacted with this new med? I think I was over dosed on estrogen and maybe I need more progesterone and to just continue back on the climara patch. Please share your thoughts!! Thanks!! I will call the doc tomorrow and I'd like to know what I need to ask of him.Tedi
