When I have the common cold, I want it gone immediately. Although I haven’t come up with an “immediate” solution, I do have a regimen that works really well for shortening the duration of a cold. If you start this regimin at the very first sign of a cold you could keep the cold down to just a day or two. If you have something worse than the common cold, this will likely help, but you should also see your doctor. Diseases worse than the common cold should be evaluated by your doctor.
