Green Chartreuse is great too (but expensive).
Actually, decongestant cough medicines have another use - enhancing fertility in men! A co-worker and his wife tried to have kids, and finally they went for tests. Turns out his semen never liquified after ...er... being deposited, so the sperm never traveled anywhere. The doctor recommended a few doses of cough medicine. Bingo!(This was several years ago, so maybe the ingrediants have changed.)
Jack Daniels and Nyquil does the trick!
Given the birth rates ..... I think a Prom dress may work too.
