Concentrate Lemon

Why does concentrated lemon destroy my symptoms of fatigue, sleepiness, and loss of coordination from smoking?

I've been smoking cigarettes for about a year now and without fail smoking a cigarette will cause eye droopiness, poor coordination, slower reaction time, fatigue, sleepiness. A few times i've lost all muscle control and fell down, unable to move.
However if i eat something extremely acidic like a salt/lemon powder or pure lemon juice its as if the effects were immidieately counteracted.
Why is this?

It might because it so sour it gives your body a shock. And ifthe other stuff is an alcali the acid will counter react it.
