16:21 again. I have the permanent kind of gastroparesis and I control it through diet. Certain foods are more difficult than others to digest. Nuts are impossible. Ditto oily, fatty food. starches are the easiest. Fluids, including milkshakes, are completely fine. if its bad I will drink Ensure (which isn't bad if you refrigerate it). Its only been a few days so I wouldn't jump to any conclusions. Its even possible that this is a particular, limited, aspect of the virus you had. If you can call the doctor, rather than go in, you could get some guidance.
