For pregnant women, morning sickness is highly unpleasant, although it usually stops around the third month. There are few effective solutions, but a couple of techniques can be helpful:

– avoid getting up in the morning before eating anything;

– have breakfast in bed, or leave some fruit compote or dry toast by your bedside, so can put something in your stomach before getting out of bed;

– eat smaller meals more often during the course of the day;

– try to get some rest after each meal.

If you take Vitamin A supplements and tend to suffer from nausea, you might be suffering from an overdose. Nausea is also a symptom of a Vitamin D or B3 overdose.
