Hi, I m writing for a friend whose laptop is broken and whose phone for whatever reason won t let her get on this cite and chat with you herself. She s 28, has been sick since early yesterday (about 36 hours), throwing up, weak, can t keep anything down, trouble sleeping, nauseous. Fever has varied from a high of 101 to just a little while ago when it was 96.4, and nausea has subsided some, but still very weak. Any suggestions as to what could be wrong and how she can treat it? I offered to bring her some soup and she said she tried that earlier today and couldn t keep it down. Before you answer, how much does this cost?
