<s>[INST] My family and I have all been experiencing vomiting, diahrea and weakness today. My wife and I also have headaches, and I have a hard time going up the stairs in my home without losing my breath. Does this sound like h1n1? My wide just took my mother in-law to emerg because of the same symptome plus irregular heartbeat. She passed out on the toilet and is also very dizzy. [/INST] what you are experiencing is probably food poisoning as every one is involved. may be the food you had yesterday was spoiled. H1N1 will be presenting as fever and berating difficulty and viral fever like symptom tiredness, head ache.main issue with food poisoning is dehydration due to fluid loss in case of vomiting and diarrhea which will give rise to the above complaint like tachycardia and week ness.drink plenty of fluids like water and butter milk, take antibiotic tablet ciprofloxacin TZ trice a day for 5 days. for vomiting can take ondensetron 4 mg tablet twice a day.watch for signs of dehydration like dry mouth and tongue fatigue and low blood pressure and increased heart rate. then you may need intra venous fluid.take care. any doubt feel free to contact me any time. </s>
