The PD patients claim small doses (smaller than I am using) work on PD too to lessen progression.

Thanks for the reminder.

(I am averaging about 80mg per 24hr period now).

Some stores do not sell this, or it might be behind the counter. I know that
Costco stopped carrying the generic and previously to that, you had to show
driver's license to purchase in my state.
I found 60 tablets of generic called Mucus Relief Cough at WalMart, for $7.99.
This will last 2 weeks at the dose I am taking now.
Mucinex and Delsym are quite expensive.

I am planning on using this for a month. Then I will slowly taper to the lowest dose
that seems to work for me. It is so nice to be able to keep my feet under the covers!
And it seems to remove some of my leg pain, which still plagues me.

I have also started Melatonin, but that was before I acquired this cough. Because melatonin does work on NMDA receptors as well, as zinc and magnesium, I think there may be an additive function.

I missed some melatonin doses though at the beginning of this illness, I was too sick to
take many of my supplements. So I don't know how much it is contributing. I am using the melatonin because of new research showing it helps keep blood sugar down.

Since I do have some wakening sleep issues, I thought it might help with my
insulin resistance.

Thanks for the information about the product at Walmart. I know what she had been paying was a lot more!
