If you have a headache it will do wonders for you. If it is all you have i would try drinking water instead and waiting it out. Get a nice neck massage eat some food. If nothings working and you have Vicoden or geneeric Hydrocodone then take it but it should be a last resort. Vicoden is a narcotic which is simular to a synthetic heroine comebined with acetaminophen. The two combined work better seperate and neither are good for your body. People who take Vicoden have a tendency of becoming addicted. Some websites to check out would be: http://www.ehow.com/about_5044684_hydrocodone-apap.html http://www.drugs.com/hydrocodone.html http://en.wikipedia.org/wiki/Hydrocodone   Hopefully the combined information from this webpage and the three I posted can help you with any questions you have. For fruther info ask your doctor.
