I think the need for ample water is vastly understated. Most people are well below optimum hydration levels for their health. But it's possible to drink too much water. Once you get past 4 liters a day in a full sized male, it can be bad for you. How could we encourage such pleasure but still prevent drinking too much?
There's a fairly simple answer. Give the subconscious suggestions that it will keep track of how much liquid the listener needs per day and has already drunk. The subconscious will know how much liquid -- it's not just water that counts; all liquids count. Perhaps they not are not as healthy as water, but they count -- has been drunk. Have the subconscious decide how much water/liquid within any 24-hour period is too much. The subconscious can easily enforce a limit it's responsible for setting. [This also avoids the one-size-fits-all problem, since one-size-fits-all rarely fits the extremes who are underweight or overweight.]
The alcohol in beer has a diuretic effect, so there is that to consider as well. This is why I stated that some liquids count less than water. If the liquid is passing right through you, it has much less effect on that limit of four liters/day you mention.
