For me, the first couple of days I experience this intense high that goes away for several weeks until the beliefs becoming internalized and solid in my system, after that it only gets stronger. Your subconscious is going to continue to fight the beliefs, eventually completely letting go of all the beliefs in your mind and then accepting the new ones.
And adding more subs to the mix can slow down the time it takes.
