making sure drinking lots of water because very yellow pee can be a sign of dehydration.....alot of people tend to have very yellow pee in the morning because of this reason. You head cold could be contributing to this dehydration
Are you taking vitamins (vitamin B2 and C is known to do that) or iron supplements? That would do it. Sometimes the urine will even smell medicinal/chemical) That will happen if it is very BRIGHT. If it's brown THAT would signify a liver problem. DEEP yellow suggests dehydration.
