I was totally fine this morning and this afternoon until about 2 p.m. I ate and then suddenly I felt very sweaty, I thought I was having a hot flash since I am 42 years old and just had a baby. I continued to sweat and then vomited. I have not been able to keep anything down, not even water, since I started sweating suddenly. I called the local E. R. they said every symptom I have it exactly the same as everyone else coming in and its a violent flu going around that hits you suddenly and their is nothing you can do about it except tough it out and drink water, which as I previously stated, I cannot keep down. Do you agree with the answer I got when I called the E.R.? Do you feel like it is the stomach flu? Do you know how long this thing is lasting this year?
