It does not sound like mania but let me quote the DSM-IV-TR.

"A Hypomanic Episode is defined as a distinct period during which there is an abnormally and persistently elevated, expansive, or irritable mood that lasts at least 4 days. This period of abnormal mood must be accompanied by at least three additional symptoms from a list that includes inflated self-esteem or grandiosity (nondelusional), decreased need for sleep, pressure of speech, flight of ideas, distractibility, increased involvement in goal-related activities or psychomotor agitation, and excessive involvement in pleasurable activities that have a high potential for painful consequences." (DSM-IV-TR, 2000)

I will stop there and let you make your own assessment. There are other disorders within the bipolar spectrum, which are not manic depression. If you are distressed by your behavior, you may consider making an appointment with your psychiatrist.
