...I always come back and listen to this file. Is this normal ?
Duh! It's a Curse!
Curse files almost always have suggestion to addict you or make you otherwise crave the file, especially if the suggestions begin to weaken.
At least you picked a Curse you seem to "enjoy". Being humiliated in this way is probably fairly safe, too. Now that you know you'll always spill the beans, I bet you're being a pretty good boy these days, huh? ;)
But remember, if your Curse begins to interfere with your job or other key areas of you life, the author may have a removal file for you to use. May.
Anyway, I'm happy to you finally got the file to work for you. Just goes to show that patience and diligence really pay when it comes to listening to hypnosis files. I'm betting though that the next file you try is going to work even better.
If you only Believe in Hypnosis, It can Change Your Life.
