I was feel nauseous constantly for a week or 2 and one day I was throwing up all day and couldn't eat. I starting looking up stuff that might help and I came across lavender oil. I got some and put a drop on a folded up Kleenex and just had it sitting near me so I could smell it. It stopped my nausea the second I smelled it. I kept the Kleenex next to my bed when I slept and I actually slept through the night without waking up to throw up. I woke up feeling great with no nausea and I can actually eat. I would suggest this if you worry about taking stuff for nausea.
