You mean like cough syrup, the kind that is an expectorant?
Hey, I was going to ask that.
Yes, but not the cough syrup form. It has too many other things in it that shouldn't be taken. I take Mucinex which is over the counter Guaifenesin tablets (600 mg.)
The guai protocol, how and why it works and more about FMS is at

I tried to make this link but it didn't work...oh, well.
