Best cough medicine I have found was referred to me by a favorite cousin several years ago...Try Apricot Brandy..A bit warm, but a sip or two really does the trick...
Best I ever had was called "G.I. Gin" back when I was in the Air Force. One swig of that stuff and you just FORGOT to cough! Phamacologically, it was terpinhydrate and codeine. They won't even sell you the stuff nowadays....well, MAYBE if a doctor prescribed it...I dunno. If I ever have a cough again, I'm gonna raise a bunch of hell to see if I can get it. Haven't had a SIGN of a cough, though, since I quit smoking sixteen months ago.
Went on sick call twice in three years, nine months, twenty-eight days and thirteen hours --- once for a cough, and once with the ****ed flu. For the cough, they handed me a jug of GI Gin and I was CURED!
For the flu, a medic didn't even check my temp, just snarled at me and stuck a box of APCs in my hand. I started out the door cussing and fuming and happened to make it loud enough for a dang bird colonel of a doctor to hear it in his office. He yelled at me to get my butt in his office, asked me what I was cussing about, I told him I'd been in the ****ed service for over three years and had gone on sick call ONCE, and now I REALLY was sick, and I'd got a ****ed box of APCs. Long story short --- instead of chewing MY butt out, he made me sit down, checked my blood pressure and everything else, gave me some TERRAMYCIN, and told me to come back to see HIM if I wasn't feeling better in a couple of days. As I left, I heard him chewing the entire A** off of that medic. Shoot, that alone made me feel good...and the Terramycin had me WELL in three days.
