  nounThe everyday word for nausea: the feeling that you are about to throw up or feel sick, as from illness, bad food, or motion. This is the word you will almost always want.
  なんだかめまいと吐き気はきけがします。↗

  I feel sort of dizzy and I feel like throwing up.
• 嘔吐おうと
  nounThe Japanese title of Sartre's novel Nausea; as a common noun it refers to vomiting itself rather than the feeling, so it is seldom the word you want here.
• 悪心おしん
  nounA less common word for nausea or the urge to vomit, met chiefly in medical writing; in everyday speech 吐き気 is the natural choice.
• 嘔気おうき
  nounAlso means nausea, but it is less common than 吐き気 and seldom the word you want in ordinary speech; 吐き気 is the default choice.

For the physical feeling of wanting to vomit, use 「吐き気」; 悪心 and 嘔気 are less common near-synonyms of it, while 嘔吐 is the title of Sartre's novel rather than a word for feeling sick.
