No APPETITE! Stomach Flu?

Today is the 3-4 day of having the stomach flu and I am starting to feel a little better, although my appetite has not improved. I feel like I am hungry but whenever I think of eating I get a queasy feeling in my stomach. My case of the stomach flu was mild (no throw up) and my appetite is not improving. How long do you predict it will take for me to get back to 100%? With minimal stomach noises and maximum appetite?
