The term 'over-indulged' typically refers to excessive consumption or indulgence in some activity or behavior. The antonyms for this word can be characterized by moderation and restraint. For instance, the words under-indulge, abstain, control, curtail, and limit all carry the opposite meaning to over-indulge. When we abstain or control ourselves, we exercise self-discipline and avoid going overboard in our indulgences. Thus, if someone wishes to curb their tendency to over-indulge, they can try to practice moderation and restraint by setting limits on their activities and behavior. By doing so, they can achieve a balanced and healthy lifestyle, and avoid any negative consequences associated with over-indulgence.
