Right before I went on Atkins I was at the doctor because of my sinuses - he gave me a sample of flonase and a prescription for it and Zurtek (sp) - well I couldn't fill the prescriptions cause of money issues right away so I was holding off. But I haven't needed to get them and the sample bottle still has some in it - only occasionally have I used it now and as an added benefit - I'm no longer waking up to being poked with an elbow cause of my snoring!!
