I am currently 6 weeks pregnant and have had horrible morning sickness. It lasts all day and can't really be cured. I've been reading some solutions online and found a lot of women use vitamin b6 and unisom to help. Curious if any of you ladies have tried it and what the outcome was? Any other suggestions for helping the nausea greatly appreciated!!
