I can sympathize with the vexing mysteriousness of "good months, then bad months." The not knowing what is helping, or what is causing the symptoms.
I found anti-depressants don't help my PMS and give me a wicked break-out on my chest, neck, upper arms and back. Strange. Since I've weaned my kids I've had good luck with a very low dose anti-anxiety medication for about ten days a cycle (one week before the period, a few days into to it as well). It's been a marriage saver to me. While I dislike taking any medication, the positive impact it has on my marriage is worth it. It cuts down on those wild swings within the marriage.
I am this month starting progesterone cream (natural) on the advice of my doctor. I'm going to take it on the days after my ovulation until a day or so before my period. I'd love to just move to taking this, something more natural/subtle than a medication. I do also take magnesium, b6 and 12, evening primrose oil, fish oil and vit d.
One other symptom I get is very tender and lumpy breasts. I don't really mind but sometimes it kicks off a whole medical scare. I was at my dr getting a breast exam during my PMS/lumpy time -- and I had to get a mammo/ultrasound and consult w/a breast surgeon. :( I am hoping the progesterone will help with this, too.
Hang in sistahs!
