Bioidentical vs Synthetic hormones »   stopping the bio-identicals

I am hitting dead ends trying to find a doctor to help with my night sweats and insomnia. My G.P. prescribed Effexor (anti-depressant) last week which worsened my sleep and left me with migraine headaches for 3 days straight so I stopped them immediately. I am currently taking estrogen cream, testosterone cream, progesterone capsules and DHEA, all of which have been adjusted in the last 5 months and still are not helping. Do I stop everything and have my hormones checked again? I have heard some women are having good luck with the estrogen patch. Any help would be appreciated.
