So feel free to chug a glass without guilt.
You can hire your own houseboat and chug along at a gentle pace from Toulouse to Carcassonne, some 60 miles away.
Poor math -- Some manufacturers try to pull a fast one by packing their capsules with filler and having you chug multiple capsules per day instead of just one or two.
But wait until you get home and discover that the $30 pills were mostly filler, so you have to chug four capsules per day, while the $40 bottle was concentrated enough to accomplish the same with just one cap.
Buy capsules with the highest amounts of bacteria you can find (not the cheapest which is mostly filler) and chug a few capsules per day during the first month, then 1-2 per day going forward.
