You know that old joke: "If men had menstrual cycles, they would have figured out a cure for PMT a long time ago".
Of course, in reality, this is no joke. As a male, I have no such cycle, but I experienced suicidal thoughts (suicidal ideation) every day for several years, caused by catching a virus that led to my chronic fatigue syndrome. This virus also caused very high mental tension and anxiety all the time, profound anhedonia (loss of the sense of pleasure in life), depression, plus the usual gamut of CFS symptoms
Miraculously, I finally figured out the cause of the anxiety, suicidal thoughts and anhedonia. It turned out that these were due to brain inflammation
(inflammation caused by the viral infection). In fact, brain inflammation probably underlies many of the problems of CFS.
More to the point, I was thankfully able to devise a simple way to treat this inflammation, with natural supplements.
Once you treat the brain inflammation, the anxiety, anhedonia and suicidal ideation will largely disappear.
Now, since inflammation is also the main cause of many symptoms of PMT, therefore there is a good chance that the same anti-inflammatory supplements that helped me will also work well for you. The anti-inflammatory supplements that eliminated these dire mental symptoms are:
Curcumin 1000 mg
Alpha Lipoic Acid 500 mg
Propolis 1000 mg
Curcumin is a herb, Alpha Lipoic Acid is an anti-oxidant, and Propolis comes from bees.
If you take these 3 anti-inflammatory supplements twice a day, with a meal, they will greatly reduce the brain inflammation (and sinusitis or headaches, if you have these), and as a consequence, will greatly reduce the anxiety symptoms, suicidal thoughts, as well as the anhedonia. For me they were a miracle.
All of these safe supplements are easily obtainable in your local vitamin store, and are fairly cheap to buy.
Technically, these supplements reduce inflammation in the brain mediated by the NF-kB and COX-2 pathways.
It is probably the estrogen cycle that is behind your symptoms. Estrogen is considered a pro-inflammatory hormone. So the higher the estrogen levels, the more inflammation you will experience. Inflammation is high in CFS anyway, but add estrogen and the inflammation get even worse.
Here is a graph (the red curve) of the estrogen cycle: http://188.8.131.52/biology-forum/about4749.html?hilit=Heat exhaustion
Does this roughly follow your symptoms?
By taking the above supplements, these should prevent any brain inflammation occurring, even when estrogen levels are high.
You need only take these supplements when you experience symptoms. In my case, I take them all the time now (as my inflammation symptoms are always there, unless I take these supps).
Note: I cannot say for sure that this will work for you. But I really hope that it does. I am trying to help, because I have been through this same hell, and I know exactly what it is like. And I suggest it is not directly do with menstruation, but rather brain inflammation. The menstrual cycle just ramps up this inflammation processes.
If you want to read more about brain inflammation and its casual conection to anxiety, depression, etc, see the research of Dr Gina Nick. http://www.sicksyndrome.com/dr_gina_nick_bio.php
Gina Nick offers some other ways to tackle brain inflammation, which you might also consider employing. I came across Gina Nick's resaerch only after I worked out the above protocol; such a shame, because this would have saved me a lot of trouble and misery.
By the way: even for those with just regular PMT, it is worth trying out herbs that reduce brain inflammation on your bad days.
And anyone with chronic fatigue syndrome, male or female, may benefit from taking anti-inflammatories to reduce brain inflammation. It is definitely worth experimenting with this.
