Magnesium deficiency, vit b6,b3,b5 ,k deficiency can all cause pregnancy sickness. It's worth a try to see. it will take a bit of time to get your levels up to where they need to be, so don't get distraught if you don't see any improvement in 1st day! Liquid B complex 3 times a day under the tounge is a good start(with no added vit d). ... and fulvic acid at the same time for the magnesium (health food store or online- again, no vit d in it).
Many times hypervitaminosis of vit d can cause it. Vit d is a prohormone and can cause hypercalcemia. The best thing to do is to AVOID vit D in all forms... supplements, seafood, flax, codliver oil, D enriched milk,(use rice milk without d, half and half watered down, or protein shakes mix for your milk) all enriched grain products (cereals and flours) (but oatmeal is ok),No SOY of all kinds,no egg yolks, also mushrooms, coffee and tea. Trust me, your body can make the vit d you need, but too much is a BAD THING. There is WAY TOO much added vit d to our foods.
Lyme disease can cause nausea and vomiting during pregnancy. But reducing vit d in your food intake will help lyme and nausea both.
ps...any nausea drug that causes headaches, dizzyness, bowel problems, aggitation, dry eyes, mouth, racing heart, etc...is affecting your central nervous system. yes, I beleive it will cross over to the baby and it is not worth it. All those ladies who were given thalidamide for nausea during pregnancy years and years ago were told it was safe
- by their doctors - and ended up having babies with no arms and legs. They've actually proven more people die of prescription drugs than all street drugs combined. So phooey on doctors that give out "safe drugs".
