Regeneration questions?


I have been running Regeneration for the last week or so because I am determined to rid myself of any unresolved trauma or toxic beliefs I have. That said I have noticed that at times I can become quite irritable and even a bit confrontational. Not to the point of starting a fight but I have always avoided any sort of confrontation in the past because of fear. Is it fair to say that me feeling less anxious about speaking my mind is a sign that the subliminal is beginning to work?
Also I read in another post how someone I believe was @Fire said how healing can be a slippery slope what time from is recommended to run Regeneration? Six months?
