Seabands ?

Worth trying or not so much ? Please tell me your experiences and thoughts with this. As I am violently nauseated and throwing up all day and night... Dicligs, zofran, and b6 only are helping for just a short amount of time until I started vomiting again. Any other thoughts or opinions on other ways to fight these feelings away would be greatly appreciated. This is baby 2, and was sick all day everyday with baby 1, even up until they literally did emergency ceserean and cut her out of me.
