The answer to that question is definitely yes. In fact, they work so well they were banned in advertising in 1958. An experiment done at a movie theater flashed “buy popcorn”. It was very successful and increased popcorn sales vastly.
Shortly after the FCC banned subliminal advertising.
So yes, subliminals work. You can use them to reprogram your subconscious mind to change anything in your life. If you want to break a bad habit or attract any desire you can reprogram your subconscious mind to believe it is true.
Once your subconscious mind believes something is true, no matter what it is, it will automatically set out to make it true in reality.
