HELP!! I have a terrible cough that I've had for a week and can't seem to get rid of! I plan on asking about it at my Dr appt on Wednesday but I hope it's gone by then. I have tried cough drops, tea with honey, and just tried some cough medicine tonight and so far I haven't had much luck with any of those!
