Answer & Explanation:
1. Alcohol acts as a depressant on the central nervous system (CNS), which means that it slows down brain functioning and impairs cognitive, motor, and sensory abilities. Mr. M.'s alcohol abuse has likely affected his ability to deal with customers and coworkers by impairing his judgment, reducing his ability to concentrate, and making him irritable or reckless. His alcohol consumption may also affect his communication skills and lead to poor solvency of problems.
2. Mr. M.'s self-assessment may not be accurate since he has already increased his drinking and is unable to stop drinking even during the day while he is looking for a job. This suggests that he may be struggling with alcohol dependency and may require professional help to manage his alcohol use.
3. Mr. M. is facing several stressors, including financial problems due to the loss of income, job insecurity, family conflicts, and the demands of raising three teenaged children. Mr. M. may also feel pressure to cope with these stressors and may turn to alcohol as a way of self-medication to alleviate his stress.
4. Mr. M. may continue to increase his alcohol intake as he develops tolerance to alcohol, meaning he needs more alcohol to achieve the desired effect. This is because the brain adapts to increased levels of alcohol and requires higher volumes to produce the same level of euphoria. Additionally, Mr. M. may be using alcohol to cope with his problems and may feel that he needs more alcohol to alleviate his stress.
5. If Mr. M. continues to drink excessive amounts of alcohol, he can cause severe damage to his liver, resulting in liver cirrhosis. This condition involves the gradual destruction of liver cells and scarring that impairs liver function. Symptoms include fatigue, loss of appetite, and yellowing of the skin and eyes. Without medical intervention, liver cirrhosis can be fatal.
