So I recently discovered Cheratussin AC is legal OTC, per request (behind the counter) , and usually from indie pharmacies.
Per the label of the bottle:
"Under Federal law, Cheratussin AC is available without a prescription. Certain state laws may differ".
I'm sure this is old news, but to anyone needing the proverbial "fix", it's a great, great thing. To all others, flame away I suppose.
