No, I didn't ever get a reply. It's worth just trying any old combination. There is another amino acid supplement that I use sometimes and that someone else here uses faithfully and is sure it has lightened her symptoms, and that is GHP by Nutralife. I can't swallow six of those pills, my throat seizes up and refuses! so I just take one a day. I think it helped my sleep when I was choking down six, but it didn't seem to help the nasty sensations and urge to move.
Another thing to look at is your vitamin D and ferritin levels. Low Vitamin D levels have been associated with RLS/WED, so get your level above 30 ng/ml. If your doctor won't test or you can't afford it, I suppose you could take a supplement anyway, but I advise you to get tested first to be sure you''re not high. Most North Americans are low in D, tho; perhaps northern Europeans too but I haven't read that. I take 3000 or 4000 IU daily, which is quite high, but my symptoms get worse over about 2 weeks if I drop down to 2000.
Ferritin is a blood test you really have to spring for if you have RLS/WED. Levels of this protein in non-RLS people can be as low as 20 ng/ml without ill effect, but levels under 50 have been associated with increased severity of RLS/WED and an increased risk of augmentation on the DA (parkinsons) drugs. Some WED/RLS specialists now recommend aiming for 100 ng/ml. Levels can be raised in many people (not all ) using oral iron supplements (I take 600mg ferrous sulfate daily, with vitamin C which is needed for absorption), and in those cases where levels are raised, the patient often notices an improvement in symptoms.
I caution you to observe yourself from a distance and ask yourself why you feel lucky to be getting as much as 3-5 hr sleep. That's a paltry poor amount and will be impacting all aspects of your life, including the ability to think straight and make good decisions. I know how we get to think it's great - by going with even less! but this is not normal, and your aim right now should be to re-acquire a normal life, including sufficient sleep. There is a danger of accepting a lower quality of life than is available to us, simply because the quality of life has been eroding so slowly that we get used to it.
3-5 hr sleep is not enough.
You don't say if you;re taking medication. Either you need to start or you need to change what you're using. Most people can find relief and get their lives back in order, so do some more research on this disease that's taking your life away ! This board is a good place to do some initial digging. This document is a good summary of treatment options, though it doesn't mention the D or the latest advice about ferritin because it pre-dates that research: RLSF Medical Bulletin (2011 version)
Aimed at healthcare providers, written by physicians, this document is very useful for patients who want to understand the disease.
