I suffered from sleep disorder (jumping up from sleep) for quite a while until recently. Two years ago I saw on TV a story about how Iron supplement has been shown to relieve 'restless leg syndrome'. From my little bit of scientific knowledge, I put two and two together; my symptoms were neurological and so is restless leg syndrome. So, I decided to try Iron supplements. It worked instantly. I started sleeping like a baby each night I take Iron.
I had also made the connection earlier to vitamin C and alcohol. Every time I drink alcohol, I get severe episodes. When I take vitamin C immediately afterwards it alleviated the symptoms. So I figured out that alcohol must be washing away vital nutrients such as vitamins from the body, which makes sense, because alcohol is a natural solvent. Now I take both vitamin C and Iron supplement before bedtime, and I sleep very well with no episodes.
I have no doubt that these nutrients support the electrical/neurological functions of the brain, diaphragm, throat muscles, as well as sensitivity to chemicals which cause mucous oversecretion. Apple cidar vinegar, which another contributor mentioned works because it is loaded with vitamin C.
Remember, for this to work well you have to play with or adjust the dosage to find the right one for you. Vitamin C can be tolerated in high doses by most people but watch your Iron intake very carefully.
By the way, it was very helpful to read all the previous contributions. Now I can join the dots.
God bless you all.
