Saline solution serum is a lifesaver!
I had food poisoning last week. I vomited all night because of something I ate at a cheap restaurant. I was so tired and dizzy that my roommate took me to the hospital first thing in the morning. I was still nauseated and wanting to vomit. They took me at the ER and gave me a saline solution serum and added a medication to it. By the time the serum was finished, I felt so much better. The nausea was gone and I was less tired.
The nurse said that I must have been very dehydrated because I never had to go to the bathroom after the IV. All I know is that I would have been very, very ill without the sterile saline solution.
