If I remember correctly, Prozac has some type of effect on your nervous system or something in order to calm you down. In my mind, I can see a link with that and the perception of not being high. You may not feel your high because you are too relaxed on Prozac. Do you have a prescription for Prozac? If not, it is recommended you STOP taking it. Also, if you drink excessively, your high sensation will become dulled while intoxicated. Don't you know? Cannabis is more of a solo herb.
