Nausea is a general symptom and has many possible
causes. Do you have any other symptoms? If you are simply feeling nauseous, this can be due to anything including upset stomach, dehydration, stress, ulcer, heartburn, food allergy, etc. As far as saying you have "too much candida," that is also a very general statement. There are a variety of candida infections from vaginal candida to thrush, both of which produce noticeable physical symptoms beyond nausea.
