So since 6 this morning I have been puking unable to keep anything down including water. I am pretty sure it's a virus but I'm scared that I am already dehydrated. I feel very light headed and my stomach hurts from puking. I just called my doctor waiting on a response back. Have any of you experienced this and they told you to go to the ER? Hoping it's not that serious. I even took my nausea medicine and it didn't help.
