These thing are so freakin amazing! My friend put me on to them like 3 years ago and they are the only thing I use when I have a cold or sinus issues. They work instantly and take any pain, stuffiness, and sometimes the actual cold away instantly! They are gel form so you don’t have to worry about taking nasty tasting coated pills. The only thing I don’t like is that they are kind of big so sometimes they can be a bit hard to get down so you just have to drink a lot of liquid when taking it. Other than that they are amazing and a definite must buy!
