I just came down with a chest cold yesterday... and I can't stop coughing, and I haven't taken anything for it because I didn't think Robitussin would be safe to take. I think i remember my doctor saying that it wasn't safe at 10 weeks.. but now it's like 11:30 at night and I'm dyinngggg. it's so annoying to be coughing every minute. water doesn't ease it and I don't have any cough drops...
