I just fought off a sinus cold with immune tea, green juice 'smoothies', Zicam, neti pot, and humidifier - really, I had just started feeling yucky and started with all of the above. It seemed to help, as it did not develop beyond a few days of sniffles and a tiny bit of a scratchy throat.
On the other hand, the next week I got hit with the flu <insert rueful chuckle here> I think my immune system was down from all the other germ-fighting. I honestly haven't had a fever in 6 years, but this got me. It wasn't terrible, but left me with a sinus infection.
So, I started more tea, neti pot, humidifier and zicam again. For comfort, I think the humidifier is the best, with the neti treatment a close second. Mucinex is really great if you have anything that you're coughing up - it's not a cough suppressant, though, so if your cough is keeping you awake, try something else. Sleep, fluids and healthy eating will do a lot of good, too.
Hope you feel better soon, no matter what you take or do!!! Being sick is just no fun at all!!!
