I am pretty susceptible to the effects of alcohol. The day after a night out of booze, the thinking seems really fuzzy. The reaction time is slow and it just feel really dense and out of it. Imagine only 2 and a half or 3 drinks and already feeling sick, headache, nausea, sensitivity to light, etc and getting this "dumb" feelings. Getting hangovers in the first place is not ideal, does it mean that the body's reaction indicate some sort of inability to handle alcohol ?
