Reliefband for nausea?

Hey ladies! Has anyone tried this and had it work? It’s a lot of money and I’m skeptical. I have HG so my nausea and vomiting is very severe and I’ve tried the sea sickness band things and they did absolutely nothing. I was on medicine my first two pregnancies bc I kept ending up at the hospital. Just curious if anyone has tried this? I obviously don’t want to waste my money but I would also spend the money if it worked and was going to help me feel better. I wish they had a trial option! Haha
