Girls, urgent! I wrote a post that I got sick and they prescribed antibiotics! Didn't want to get an injection (we're on IV), but had to! As I knew! Now my little one started diarrhea, I'm panicking! Called doctors! They said drink Metamucil Forte and drink 300 ml of liquid in 6 hours! But we're drinking very little water anyway! And Metamucil Forte is so sour that she throws it back! She's weak, sleeps and poops! I'm having a breakdown! How can I stop diarrhea? I don't even want to call them an ambulance anymore, maybe someone has experienced something like this, what did you
