From another momma who is constantly dealing with hormone swings and years of avoiding the traditional remedy for pms, anti-depressants, I have researched a gazillion things.
What you are feeling is REAL and VALID. The solution will be up to your own knowledge of your body. For those of us in our thirties there is alot of research coming forward about deficiences in our supplies of progesterone and estrogren(predominantly estradiol). In the last three months I started taking bio-identical progesterone($21 a month and prescribed by a doctor) on the 14th day of my cycle at night. It is helping alot with my pms symptoms that happen from day 14-28(day 1 is your first day of your period). I sleep alot better and don't wake up with a dent in my forehead and have stopped being cranky.
There is some research that I am working on myself for those of us who have had our tubes tied or clamped, tubal ligation, in the depletion of estradiol, which is one of the three types of estrogen that is made in our ovaries(with our tubes clamped it sends weird messages to our ovaries, or that is at least the theory). Alot of folks link this to post-tubal ligation syndrome. I am currently taking a supplement, modestly, that is helping me raise my estrogen but I am watching it ubber closely as I don't want to swing too far. So far, I am feeling a noticeable difference.
This has surely been one of my biggest challenges as an adult woman- hormones. And I struggle with the lack of interest or education with our medical and naturopathic doctors. I found a lot of help reading Ageless by, believe it or not, Suzanne Somers and her barage of medical advisors. Also another book that really helped me understand my hormones, it has a really odd name, but it was really helpful to me, It's My Ovaries, Stupid! by Elizabeth Lee Vliet, especially in understanding my cycle.
I hope this helps and sorry for the distracted flow in writing, lots of interuptions. good luck!
