I guess what you have experienced were the so called resistance. As for which kind of resistance it is, I am not sure myself. You could read Shannon's post about resistance if you have the time. This is the link to the post I talk about https://subliminal-talk.com/Thread-Types...-Spot-Them
From what I often read here, when you meet some kind of resistances, you should either reduce your exposure or increase it. Giving up (stop using or changing subs halfway) are out of the question. Since you have met with a strong resistance, I am gonna assume that you are listening to 5.5G sub or newer. Those are the one strong enough to trigger resistance.
You could reduce your exposure by switching the track in which you are listening to to a more gentle format (from hybrid to ultrasonic and/or from ultrasonic to masked). If it does not work, you could reduce your volume. And if it still does not work, you could try to reduce the amount of time you listen to the sub. In another word, reducing loops per day on to the amount of what is being prescribed in the product page. Reducing exposure are usually needed by those who have strong personality. Those who does not like being told what to do.
Another way to deal with resistance is to confront it instead by increasing the exposure. Switching to a stronger format, increasing volume, increasing loops per day on, increasing day on or reducing day off per ASRB2 cycle. This way, sooner or later, the resistance will be eradicated and your subconscious will be able to execute the script better and faster.
Sometimes, when you have listened to a sub for long time, your subconscious can get bored so it does not want to execute it. If this happen, what you need to do is to take a break from listening. You could take 2 to 6 weeks off before listening again. You could also listen to another sub first and then come back after you feel like your subconscious boredom has ended.
Please note that subconscious boredom happen after you listen to subs for a long time. If you want to stop listening or change sub before you finish it, it is most likely a resistance rather than boredom. Anyway, I am a new user and this is technically my first ever post on this forum so please take my advice with a grain of salt. Hope this help.
