How has your symptom journalling been going? I have been reading up on women's hormones. My wife has an excellent book by Dr Vliet. The connection between women's hormones (ovary hormones) and brain function is strong.

If you do get going with your journal, it would be good to include your cycle too. You may find that the two weeks before your period are your better weeks. You brain will have more progesterone available during those weeks. Progesterone is a neuro-protective.
