I felt my throat getting sore this past weekend so I popped some Cold FX and continued to follow the directions on the bottle, taking 2 a day (I had extra strength). I am now getting over probably one of the worst colds I've ever had. I think this product is mind over matter, honestly, and do not believe it works at all. I think for those it works for, it's a coincidence completely. I think CBC's Marketplace did a study on these and found they did absolutely nothing as well. Just brutal how consumers (including myself) fall for this - I think everyone would love to find a cure for the common cold, but pharmaceutical companies just continue to make so much money on medicine for cold and flu, that they would never even think about trying to find a cure! Complete waste of money.
