I have never been convinced that those effects were anything other than 
subjective and ephemeral, but.... "YMMV".  That said, I used to adjust 
the A relays on my connector switches for correct pulsing and B relay 
residual screw for correct release time by ear.  I was in my mid/late 
teens at the time and as of that time had never consumed any of the 
substances you are referring to.

As with any marginal condition that is investigated "with a blindfold on 
by experiencing the elephant by touch", changing something that is not 
fundamentally the cause can make the difference between something 
working or not but just as it may seem to solve the problem, the problem 
may re-emerge when something else shifts the balance slightly back over 
the line.  But I believe you know this too even though you did not state 
it in so many words.
