I Had A 24 Hour Chills, Fever (102), And Mild

I had a 24 hour chills, fever (102), and mild nausea. I could not eat and did not drink much. Twice, I fainted as I was vertical and felt nauseous. (This has happened in the past.) The second time, I threw up a small amount of fluid. The next day, my fever was down to 99 and I was able to resume eating and drinking. I have continued to rest, eat, and hydrate. Now, 3 days later, I'm still dizzy, and feel weak. Is this a normal recovery time? I'm a very healthy, active person.
