If you want to take the chance with the syrup, the tussionex is the BEST, but VERY expensive. The reason is, that it is suspended and time released so you get a FULL 12 hours of cough relief. The bonus is that it's excellent for pain relief as well, better than hydro/apap, again because of the time release property, IMO. Could you get an RX for the syrup from your DR? My experience is that DR's don't have a problem with writing a script for a few days of tussionex, particularly if you're having trouble sleeping.
