this mixes quite well with the other thread a la "what have you done while blacked out"
with alcohol, beer is one thing but with hard liquor, my stomach is just much weaker and there's always a specific " oh shit that was too much and I am going to vomit." but that's nothing really in comparison to the too much for many other drugs, yet it agrees with the other statement that simply
"too much is when it becomes unpleasant"
