Great price for such relief! I was skeptical about taking it at first, since the last thing I tried to take had very bad effects on my body. I was surely surprised when everything went well, and fast too! It kicked in I would say within 10-15 mi nutes of me taking it. I could breath through my nose again, the cough was gone and no more soreness in my throat! I says lasts 4 hours, but it's been 8 and I am barely feeling the symptoms return! A success of a product in my book! I am a new fan and will be for a long while, you should check them out too! Mild menthol flavor makes you feel soothed immediately!
