Recently, after 1-2 hard alcoholic drinks i am inebriated. i even passed out at dinner after one martini! why might this happen?

Alcohol: Acute drunkedness can cause vommitting at times seizures but generally people sleep it off. Long term alcohol use will cause liver and possible heart damage not mention a host of social problems and possible car accidents ... Not a good thing.

Reversed tolerance: This is called reversed tolerance, it is a sign of advanced serious effect of alcohol on the liver, the liver is unable to metabolize alcohol. In the uncommon situation where you are not a drinker and surprisingly you develop this reaction, then it is possible you are having some liver problems. In either situation , you really want to see your doctor and completely stop alcohol.
