You can try doing the lachesis with some consistency and see if that helps too.
Sure, you can use herbs as well....but I'd look at correcting imbalances first and foremost.
I have been taking vitex, but I don't know how much it helps. Extra omega oils and calcium/magnesium does help when I remember to take it. Exercise helps, especially if it's an early walk in the fresh air. Lately I nap a lot, it kind of worries me because I know I get enough sleep so the tiredness seems strange.
Also my symptoms have decreased to almost nil since I changed my diet. I used to have SEVERE pms and menstrual symptoms-skin breakouts, mood swings, tearfulness, diarrhea, really ouchy cramps, nausea, sometimes vomiting.
Since I cut out wheat, dairy and sugar my period almost sneaks up on me
I've been living at my friend's house for the past month and there is cheese and sour cream and sugar here that I would never buy when I live at my own house (I never cheat on wheat cuz it makes me sick immediately now) and I really noticed a difference when my period started this week. I was way crankier than usual and had more intense cramps that lasted longer than my new norm.
The diet changes I made were in the context of the blood type/genotype diet. So the changes I made may not necessarily be the same for you, unless of course you're an O blood type like me
I use a Period Calendar to keep track of my cycles, moods and PMS symptoms. When I note that it's that time of the month, I try to take things easier than usual. I go for a walk, take hot baths, rest more, eat healthy and nourishing food. I notice that stress is a big trigger for my PMS moods, so I watch my stress level very carefully. Also I think a lot of anger, sadness etc are stored in our subconscious mind. Those emotions get triggered more easily because we're not feeling great and we're ultra sensitive. Meditation, breathing exercise, writing journals are all great ways to help me get in touch how I feel inside.
