I gave up on using carbocisteine and cough syrup to cure my cough and decongestants also don't work for me. On the other hand, Alka Seltzer plus really works fast when it comes to getting rid of mucus on our lungs and throat. This over the counter medicine works really fast. It looks like a giant tablet and you will place it inside a glass of water. The tablet will melt fast and the water will turn into a lemon flavored fizzy drink. It is like curing your cough and cough with Sprite of 7-up!!! Here is a discount coupon for their products!!Please Log In to view this link!
