Good point. The antivirals are short term, but I have a feeling they could get toxic. i don't have a potassium problem in general, but that is a realistic danger.
luckily, I have successfully eaten the tomato soup rice I made, and dh brought home pork broth (won ton soup base) and white rice from a Chinese restaurant, which I also kept down. so at this point, I think severe dehydration has been averted. Dehydration by excessively aggressive posterior expulsions is still possible- but my only solid food has been rice. So hopefully, that sill have prevented that.
i think I will try sautéed potatoes in the morning. I'm getting hungry thinking about them, which is good because I haven't been hungry either. Maybe ive passed the worst, at least GI-wise. I do be coughing, though!
