What might result from a "surfeit" of indulgence?

A "surfeit" refers to an excessive amount of something, often leading to overindulgence. In the context of indulgence, having a surfeit suggests that one has indulged too much, whether it be in food, drink, or other pleasures. This excess can lead to negative consequences, such as feeling unwell or experiencing regret over the choices made.

Thus, the outcome of a surfeit of indulgence is clearly characterized as overindulgence itself, leading to possible discomfort or adverse effects. The other options relate to moderation or positive habits, which do not align with the implications of having a surplus or excess. Therefore, overindulgence is the most fitting result in this scenario.
