is a Robitussin cough DM gel cap. There is also Coricidin HBP, but that has chlorpheniramine added to it. Also hard to find here, because of the abuse by kids.

I could not find it in stores near me. I have limited shopping time because I am still sick. I sent hubby out, and he could not find it.

You might find it on Drugstore.com A friend of mine works at RiteAid and she said they haven't had Robitussin cough gels for months. (this might be a regional thing... )

I don't think the guaifenesin is working on the feet. I don't know why, but I think it is the DM. I've never taken so much before.
The first couple of days, I was a bit "high"...but now I have no effects like that. At first I had to take some Benadryl 25mg because of the endless sneezing. But I am no longer using that either.
