Aww, Vegetableman, i feel your pain. I had salmonella food poisoning several years back and i was never so sick in my life. Do you have anyone with you? If you get too dehydrated, go to the dr or ER for some fluid.
I ended up in the ER 3 times in 4 days for fluid with a bp of 70-80 systolic each time. I was unimpressed with the ER docs--they kept saying it was a stomach bug, gave me a bag of i.v. fluids and sent me home each time. But they gave me fluid which kept me from dying so i am grateful for that anyway.
I was 2 wks post surgical and the dr who did the surgery was on vacation at the time. When she got back, a few days after i got sick, she was very concerned for my long term health and it was only then that i realized what a skeleton i had become. (I was not really checking the mirror at the time--i had my hands full crawling back and forth between the bed and the bathroom.) i lost 15 lbs or so in a week's time.
Take care of yourself and hope you soon start to feel better!
