Yes, deranged in medical terms means abnormal, and likely, in your case, there must be elevated liver enzymes like SGOT (serum glutamic oxaloacetic transaminase) and SGPT (serum glutamic-pyruvic transaminase). Likely, the cause is alcohol only. It directly affects one's liver. In the short term, such damage recovers within a week period, but chronic high consumption may lead to permanent damage. So you should repeat LFTs (liver function tests) after a week. Also, get an ultrasound of the liver done to look for chronic damage.
Have you consumed any other drugs the day prior?
Alcohol is the far most common cause.
