It seems as though anyone can obtain a tolerance to any drug; I have seemed to notice, even coffee! I remember the first sip of coffee I had and thought how great that kick was and then the very next day I had a cup and not the same thing, weird how that happens. Anyway.....
My doctor always instructs to take breaks from medications, so as to lessen the tolerance, would be my guess. And now to the point......
I have noticed that you posted that you were not achieving the desired outcome from taking these pills and I wonder if you have tried taking them on an empty stomach right away in the morning and then wait for an hour before having a glass of juice. Maybe would be a good time to try a fast for the day and then try taking another dose the next day and that should do the trick for you, if that made any sense. So, taking a dose on a completely empty stomach should work well for you, good luck.
