This is the third one I've purchased. (I lost the first one, and I never want to be without it.) I now have one for home, and one for my purse. Not only does it relieve nausea, and a couple of other uncomfortable stomach discomforts immediately (with the very first pulse), but it is very effective at relieving my severe and frequent anxiety. (I researched this and found there is good scientific evidence for why it works for anxiety. ) I'm a very nervous flyer, and I recently took a very turbulent flight where other passengers were sick, and a few cried out in fear.(Good grief!) But I was perfectly comfortable and calm with my Reliefband on!
