Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
No, this is not a sign of liver failure, and drinking alcohol continuously for one semester does not cause that serious damage to lead to liver failure. As we grow up, our alcohol dehydrogenase enzyme reduces, and the metabolism becomes slow, So, the alcohol hits you much earlier, than it used too before. This is common, and you should not worry about it.
However, for your liver health, I will advise you to not drink everyday and cut it down to 1-2 drinks every week. In the longer run it may cause cirrhosis of liver if you continue like this
Hope this was helpful,
Regards,
Dr. J
