What Causes Nausea Ans Faint Feeling All Over Body?

This morning, I woke up and felt fine. After a cup of coffee, I felt some nausea but it passed. Shortly after, I felt very faint and had lost all color, my eye was twitching but causing me to physically jerk my right side of body. I didn t feel totally present in my body. I went to bathroom and color came back. 10 minutes later, went through the same experience with feeling faint and eye/body twitch. I ate eating soup and drank water but I don t feel much better. In last 24 hrs, I have eaten my lunches and a small supper. Do I need to see my doctor? Thanks for your help!
