You may be...,: Significantly dehydrated. Try drinking a large glass of water every hour during the day, & be careful of your slat/sodium intake. Your urine should be a very pale yellow or clear if you're getting enough fluids. If this doesn't help?, and you're urinating a lot, losing weight, or very tired, please see a doc to check for diabetes or pituitary problems.
