Gosh, you are suffering, and you must feel very frightened as well.
Internal shaking seems to be part of the perimenopause, and you seem to be having a very hard time of going through this transition.
I am not in your shoes, so I can't really know, what you are going through, but I do feel your anxiety and utter frustration of what you can do to relieve your situation.
If you feel you have to take something to get you through, then do so, but remember, that they only temporary mask the symptoms.
The worst symptoms of the menopause is during the perimenopause, one day Astro, all these symptoms
You body is going through hell, but you will survive this.
I would suggest you try some relaxation tapes, also do some self talking:
Say: I am going to get through this, it is very hard on me, and I feel sooooo horrible, but one day soon, these horrible symptoms will have had there day, and eventually go away.
I must do my bit to help my body through this difficult time.
Do this relaxing throughout the day, often.
I will tell you something that I took to get me through, this period, it worked for me, it may not for you,
but it must, be worth a try.
Phytoestrogen food have a hormone like qualities.
They mimic the effect of estrogen as a low dose, and block human estrogen at high levels.
I ate phytoestrogen rich food, and also, I consumed soya yoghurt.
I was well aware, that soya was a goitrogen, I took the yoghurt 12 hours away from my Levo pill.
Soya yoghurt is also a phytoestrogen.
It worked for me..........................
If it helps you, other people are going through what you are, perhaps there is a forum you could join, it makes going through this a lot easier, when sharing your feelings.
Take real good care of yourself, you will see this through, you are having a hard time of it, but you will be fine.
Phytoestrogen rich food:
dried dates-apricots-pistachios-sunflower seeds- peanuts-almonds-cashews.
There are more of these foods, but at this hour of night, that is all I can think of..
