During a manic phase a person may experience feelings of euphoria, feel overly optimistic and have an inflated self esteem. Some may lose their normal sense of judgement that can result in over spending sexual promiscuity and/or unnecessary risk taking. People experiencing mania can also at its severest, experience delusions and hallucinations (Zyprexia Olanzapine, 2007). In the early stages of a manic episode, people experiencing it may not have any insight into what is going on, and when the mood change is pointed out to them, they can become angry.
