I&#x27;m fortunate to have the same problem with alcohol.  I can get up to drunk (though I won&#x27;t feel 100% the next day), but anything beyond that stage and I start to feel ill.  Especially back in college, I remember other students regularly getting to stages well past drunk (e.g. &quot;wasted&quot;, &quot;trashed&quot;, &quot;black-out&quot;, etc.), and enjoying it, but I only ever did a few times and was always completely miserable.<p>In the end it was just my body protecting itself from the stupidities of the brain running it.
