I have been attempted to hypnotize five or so times in my life (but without using the hypnotic drugs). It never worked. Was told that if you're skeptical or if you have any doubt it actually works, it won't work for you. Sounds like placebo to me.
Just listening for some bullshit for a month will do nothing to change your beliefs either unless you already accept them. People in Communist countries listened for propaganda for dozens of years, and for the vast majority of the population it didn't work at all.
