I understand you might be feeling a bit restricted with these instructions but we have to remember that ZP subliminals are very powerful and they will unfold in you over time.
Also, I have yet to hear any professional subliminal maker allow stacking of 2 or 3 titles in your stack. I have seen one sub maker allow stacking maximum of 2 titles but even there are many exceptions to the stack.
Am mentioning this to help you gain perspective. There is growth but sometimes it is hard to see it.
Another option is to reduce the size of your stack so that you can notice results faster. I have found a 2 title stack to work very well for me. But you can imagine that a 1 title stack is even better since you only need to process 1 title and hence it will work faster.
See if you can experiment with 1 title only and see how fast your growth is for 1 month. After which you can add another title to it and then you have a 2 title stack for the next month. And so on.
Sometimes in our excitement to get it all fast, we are not considering processing time and the time it takes for the subliminals to deeply embed in us.
Also note rest days. And if you feel reconciliation, take extra rest days. All this will help
