As others have said, labels are labels but, I will give you an example of my "last" manic episode...in a 2 1/2 month period, I worked as a nurse over 590 hrs sleeping anywhere from 2 to 4 hrs a night 7 days a week average; however, there were cycles of wakefulness lasting 36 to 48 hrs before getting that 2 to 4 hrs of sleep. That was with me taking Seroquel, Ambien 10mg (2 tabs), Xanax 2mg, and Valarian Root 1590 along with my Topamax and Lithium and other Rx meds...I have now crashed and at the other end of the roller coaster. The last time this happened, I was hospitalized and the called the episode "severe". Don't know if that helps...hopes it gives some insight.
