Can anyone explain what hypomania feels like and your symptoms?

From Kay Jamison. "two aspects of thinking in particular are pronounced in both creative and hypomanic thought: fluency, rapidity, and flexibility of thought on the one hand, and the ability to combine ideas or categories of thought in order to form new and original connections on the other...Rapid, fluid, and divergent thought in the creative process".
Hypomania. Is less intense than full-blown mania. Characterized as increased energy, excitability or agitation, increased productivity and creativity, less need for sleep, more social, thoughts may be accelerated some, impulsive, possibly hyper-sexual.
