I was pretty much able to avoid morning sickness and just generally feeling like shit.
For one I am on a different diet now than with my last pregnancy. I eat Paleo and high in saturated fats, eggs and meat. Whereas with my son it was lots of carby foods and veggies. I was miserable with my son. This time I had a lot more energy, did not get sick once with sick people all around me, and just less strong symptoms, good appetite, no first trimester acne.
I notice a bit of nausea creeping up when I don't stick to my diet. I also get constipated from starchy foods.
Then I also added magnesium: https://wellnessmama.com/6065/avoid-morning-sickness/
After which my mild MS completely disappeared. I believe because of my diet my vitamin B stores are high but in case they are not one can supplement.
