I started taking 25 mg of B6 three times a day with a little food. I have to split the tablets because the smallest tab at the store is 50 mg. I read results of a few clinical trials that showed it works for some women. Pregnant women are recommended to not take more than 200 mg B6 per day. You might try it, though, of course check with your nurse triage line and check how much is in your prenatal.
My nausea is gone. I still have bloating and constipation...so I don't think that lack of nausea is from transitioning to past it. I also still do the other tricks with small frequent meals and ginger tea and gin gin suckers.
