Hi Squeaker. Big hug first.
So sorry to hear you are struggling so much with insomnia. I completely understand how worried you are as I was where you are now, for several years during peri & it's a Godawful thing to deal with. Even 7 years postmenopause, insomnia continues to be a major issue for me & one of the main reasons I have recently gone back on systemic HRT.
Insomnia hasn't killed me yet, but as with you, there have been times when I truly thought it might. It's no joke and can be a very frightening thought. My insomnia goes back more than 30 years as I have a chronic pain condition that cannot be treated, but during peri the most intense overheating began every night & that exacerbated the insomnia & still does. Since peri started there has also been inexplicable early waking that happens whether I have pain or night sweats or not. I simply wake & am too alert to get back to sleep, despite being very tired by day. Now long postmenopause, I still find it very hard to sleep much after about 3:30am and often only sleep poorly before that. But this is still far better than I was a decade & more ago.
During the peri years, on many nights, especially close to a period, I had no sleep at all. It terrified me & I amassed a library of books on how to deal with it + CD's & tried all the various supplements.
I would back Birdy's comment that meditation really can help. But you have to get into regular practice to really reap the benefits. It can improve not only sleep & anxiety but physical health - there are many studies showing amazing benefits, so if you can get back to doing this again, somehow make the time & get into a routine, it is perhaps the best health insurance measure you can take at this difficult time.
I know this is controversial, but I have to go against advice that magnesium & B vitamins are always helpful. I found both exacerbated my sleep issues when peri began. Magnesium IS said to be sedative & calming & I am all for its cautious use in those women it helps. It did help me sleep & relax for years before hormones began to go awry, so if you have not tried magnesium it
may help. BUT nutritional supplements can have unexpected, idiosyncratic effects in individuals & at menopause when the body is out of balance I suspect it is relatively easy to do more harm than good this way. I found B group vits too stimulating & that magnesium made me far too hot. The diuretic effect can also mess with electrolytes & possibly cause dehydration which can also have adverse effects on sleep.
Foxy - I'm going to say something similar about flax - again another supplement that can be amazingly beneficial to many women especially for digestive issues & one that helped me no end BEFORE peri began. Though it's termed a phyto-oestrogen, it's thought that the lignans flax contains can have either oestrogenic or ANTI-oestrogenic effects. So at a time when we're trying to increase our oestrogen levels, flax may jeopardise those efforts & I suspect, oppose the effects of HRT. I found to my dismay that once peri began the flax seeds I'd found so helpful for digestive issues actually worsened my meno symptoms including flushing, night sweats & insomnia. They also raised pulse rate & made me feel jittery & hyper. I thought flax was somehow potentiating thyroid hormone (I am on Thyroxine & T3) but after researching & experimenting with excluding & reintroducing it, came to the conclusion it was more likely lowering oestrogen levels. The following link may not be the best example of the anti-oestrogenic effect proposed in the scientific literature, but I think it's interesting.
The meaty bits are:-
"A phytoestrogen is a plant nutrient that is somewhat similar to the female hormone estrogen. Due to this similarity, lignans may have estrogenic and/or anti-estrogenic effects in the body."
"Lignans, which are the type of phytoestrogens in flaxseed, can change estrogen metabolism. In postmenopausal women, lignans can cause the body to produce less active forms of estrogen."
https://www.oncologynutrition.org/on/erfc/healthy-nutrition-now/foods/flaxseeds-and-breast-cancerI'm not advising anyone to stop supplements they find helpful - we all need to help ourselves as best we can. I'm simply sounding a note of caution & suggesting that this is a time when we need to be very vigilant to the way our bodies respond & open to the possibility that some "natural" remedies may upset the very delicate balance of the body at a time when its ability to maintain homoeostasis is already badly compromised by the hormonal chaos of menopause.
Sorry this is a bit of a meander - but anything that might help us sleep at this time seems worth raising.
