Greenish urine can mean that you have a urinary tract infection but if it's bright green, it can mean that you have too much of B vitamins. Certain drugs and some health conditions can cause urine to turn green, too, so mention this to your health care professional.
Alcohol does this by interacting with the receptors on the receiving cells in these pathways. Alcohol affects various centers in the brain, both higher and lower order. The centers are not equally affected by the same BAC -- the higher-order centers are more sensitive than the lower-order centers. As the BAC increases, more and more centers of the brain are affected. The order in which alcohol affects the various brain centers is as follows: Cerebral cortex.
Brain Chemical Imbalances after Long-Term Alcohol Use. Alcohol has widespread effects on the brain and can affect neurons (nerve cells), brain chemistry, and blood flow within the frontal lobes of the brain. Neurotransmitters (chemical messengers in the brain) are affected by long-term use of alcohol. When a person who is dependent on alcohol stops drinking, chemical responses create an overexcited nervous system and agitation by changing the level of chemicals that inhibit impulsivity or stress and excitation.
