hypomania

Hypomania (literally “under mania” or "less than mania") is a mood state characterized by persistent disinhibition and pervasive elevated (euphoric) or irritable mood but generally less severe than full mania. Characteristic behaviors are extremely energetic, talkative, and confident commonly exhibited with a flight of creative ideas. While hypomanic behavior often generates productivity and excitement, it can become troublesome if the subject engages in risky or otherwise inadvisable behaviors.
