You’ll be fine. Cal’s curse is actually a pretty gentle induction and it’s hot to listen and edge to. Stuff like this, generic hypno scripts, are mostly enabled by your desire for them to work. (If they work at all that is, some people just aren’t ‘suggestible’ enough for them to have an impact).
If your desire or interest fades, so does its effectiveness. It might take a little while, but you’ll be absolutely fine. So give it a go!
