It did help me. The key was to take it consistently every day and not skip. It takes a few days for the levels to billed up in your system and then you need to maintain it so you don't want to stop taking it when the morning sickness goes away. I did the unisom a.m. and p.m. and while I was tired at first after a few days I built up a sort of tolerance to it.
I also found that heartburn meds helped too. A lot of my nausea was reflux related and so a daily dose of prilosec or other OTC hb med helped too.
