Hi Wray, I am so glad to have found your website as I am a 40 year old women who has nocturnal seizures for the past 15years, and I have always known there is a distinct catamenial pattern to my seizures. Sometimes seizure/s between day 10-14, but mostly two or 3 days before menses.My cycle is usually quite regular, between 28-30 days. Never at any other time of month do I have seizure activity, and it doesn't happen every month, usually every 2-3 months.I think this is because of annovulatory cycles every 2nd or 3rd month. I have never been able to find a practioner who would try to treat my seizures from a hormonal perspective. I have been researching this for years, bioidentical progesterone, as I knew that my seizures are only ever hormonal. I have found a compounding chemist in Sydney that makes bioidentical progesterone and have tried it for the last 6 months. I havn't found total relief of seizure activity yet, but I found this website and realised I was told to take way too little a dose. 20mg bi- daily. I have started taking as you suggest, 100mg morn and 100mg night. I think I may need more. The thing that I need to know is that, if my seizures are caused by anovulation, and if I take the progesterone throughout the whole month, or start to take in that danger time between day 10-14, will I cause anovulation, and therefore not produce progesterone in the luteal phase naturally and still leave myself open to catamenial seizures?. Being that my seizures are mostlyday 25-28, or day 10-14, I am inclined to take the progesterone the whole month. Am I using the right amount? And the right treatment pattern? I have read your page on epilepsy and found great information, I would just like some more advice on a strategy that you think may work for me please. I am not worried about fertility, contraception, or anything but seizure control!! Please help me!
