If this is your first fast (this is my first), I would strongly recommend the B&Ps.
I wish I would have started them from Day 1 instead of Day 10.
Getting out all that mucoid plaque the first time will take a while.
Your body (tongue) will tell you when you're through.
I still have about 21 more pounds to go and my tongue is slowly clearing.
Good luck and stick to it.
