Vomiting: Repeated vomiting can cause weakness by virtue of dehydration and/or electrolyte imbalance. Causes of continued nausea and vomiting include viral gastroenteritis, pregnancy, intestinal obstruction or severe indigestion or food intolerance, inflamed stomach lining,alcohol excess,toxins,etc. I recommend going to the hospital emergency room where prompt evaluation,testing and treatment can take place
