Shortly after my post, I stopped taking it because it's $40/month & i'm losing sensory on daily basis. What a mistake! Within 3 days, my eyesight started seeing more double vision (with 1 eye)! Yes I know my body's production has been lowered by getting it from the outside, but my conclusion is it's very important at least to "my" MS.
Won't be estriol, but if anyone knows mg's of each in birth control, please post it.
