I get motion sickness really easily - car, boat, train & even in the bath tub for some odd reason. Hyland's natural is a homeopathic remedy that relieves the slightest motion sickness instantly. I take 2-3 tablets 30 minutes before I'm in a vehicle & I'm good to go. Sometimes even when I'm a little nauseous I take a few & feel better within a few minutes. I keep them in my purse & never leave home without them. I highly recommend these because being sick is a bummer.
