Nausea all day

Is anyone having to deal with nausea every day, from the moment you wake up to the moment you fall asleep? Puking in the morning, puking in the evening? I've tried eating a snack right before bed (and it came right back up), snack when I wake up, as soon as I wake up (and with the same result as the night snack).

I've also tried peppermints, because that's what my mom swears by, and it barely helps.

What was your best method for countering morning sickness?
