I was waiting to see if anyone else would answer your post before I did, who might have had the same situation. I might have a few helpful comments to make.
I have taken magnesium in the past and had it help me out of a situation of fatigue, extremely low pulse and blood pressure that had me gasping for air and resting in bed most of the time. (I was pretty scared too.) A cardiologist checked me out and suggested magnesium. He said the soil in that area was magnesium deficient, plus my diet of cheese and lots of coffee and coca-cola with poor nutrition was destructive to the magnesium balance in my diet. I was also under a lot of stress and was allowing myself about 5 hours sleep. I was not peri-menopausal to any extent at that point. I took a variety of nutrients including magnesium and recovered in a few weeks. However... I would be reluctant to suggest that your fatigue has the same cause as mine did.
You are taking two different medications, you say, so can you check out the side-effects of those medications with a pharmacist please. I also think that new symptoms should be reported to your doctor... I also have some questions about your health issues though. I wonder if people will be familiar with lowering creatine protein. I may post more later but I am feeling a bit off and tired. ... Also you need more than 5 or 6 hours sleep, lack of sleep just by itself can cause fatigue and other health problems. Dearest suggested using the site search for "depression" to me recently. You could search for that and for "insomnia" too.
Hope I'm making sense. I need to take some magnesium too, as I have felt some of that internal shaking lately too. I keep wondering if the floor is shaking, and sometimes it is me, sometimes it is the floor.
Please post again and let me (us) know how you make out. I would like to know, and knowing what has helped you could help someone else too.
As for the magnesium, I agree with what WhiteHorses has said. I have been talking about the wonders of this much underrated mineral for many years. Magnesium is highly effective in treating palpitations, fatigue, a host of nervous symptoms and can be helpful for the internal shaking, but it wasn't the total answer for me for the internal shaking. I believe, in my case, the internal shaking is a combination of internal anxiety plus hormone issues -- and it's a vicious cycle because the anxiety comes from the hormonal issues.
I will tell you what I do, but I don't necessarily recommend this for anyone else. I have some naturally compounded estradiol and micronized progesterone in a transdermal cream base. My bouts with internal shaking are fewer now that I've been postmenopausal a few years, but when the shaking rears its ugly head, I use the transdermal cream for a few days only and it helps. I get mine from Dr. Erika and The Natural Hormone Pharmacy. I like the combination in one applicator. Again, I don't take it every day because I prefer not to. I've asked a few doctors if the way I'm using it is acceptable and the resounding response has been, "Sure, if it works for you." I don't know if you want to explore this avenue, but it's always a possibility. Again, this is what works for me personally. Power Surge doesn't recommend that all women use naturally compounded hormones in the same manner.
The internal shaking can drive you to distraction. I know. I have been there for years and the suffering you describe resonates loudly and clearly.

I am in peri menopause and have had the palps, internal shaking, anxiety, and depression. What helped me most was 500 mg of Magnesium at bedtime. This eliminated the palps and internal shaking. Also Revival Soy has helped the anxiety and depression. I have a little more energy and sleep better.
Let me know how it goes.
