Seabands for nausea

W • Married to my dream boat. MC Jan 2015. Baby #1 due 1-10-16. Hoping for a healthy 9 months!
I've been having awful AWFUL nausea starting this week. I made my hubby pick me up some Sea Bands on his way home from work. Anyone else used them?
I have ginger candy and mint tea and crackers and fresh ginger steeped in water and nothing. 
I am at my wits end. Lol
