Mucus cough DM tablet at bedtime for my sinus congestion, and the DM helps my feet some. (this is generic Humibid LA DM and available at WalMart.) It is somewhat less expensive than the liquid.

I don't think it is very good however, for severe chronic pain.

The PD forum here uses it in small amounts for their dystonic movements. If you search at Parkinson's you will find many posts about it.

Delsym cough syrup is plain DM with no other ingredients.

The FDA is looking at DM products, and may start to control them more tightly, since abuse with them is common by the younger set. Expect to show your driver's license when you buy it at the register. WalMart doesn't check us, since we are gray and obviously OLD. But Target DOES.

I personally like DM... but it is not as strong as tramadol for me for pain.
