I get this sickly feeling also, I've had it for the past 8 years now somedays it becomes worser, Were i can't even stand/walk im really am light headed etc,.   it's every time I I wake up in the mornings it's a sickly/groggy feeling in my whole body my stomach turns and turns,I get the body shakes due to the sickly feeling and i can actualy feel the sick moving around up my throat and I cough.. Half the time i make my self vomit to try make my self feel good, But that just makes it worse leaving me to be sick for hours on end. It's a really horrible feeling i just want to feel good and wake up in the mornings or when ever and feel fresh not ill . I am sick to death of it.  I seen numerous doctors and none can diagnose whats wrong with me.  Please help me somebody who experiences the same.
