I am not sure it is a FACT than
bipolar spend 75% of the time depressed, maybe
for bipolar 2, but my observation, it is unique
for each person. I would be manic for up to 6 months sometimes, then be depressed for as little as a week or two. Sometimes I sleep 2 hours, sometimes 10, I don't think there is standard for how bipolar effects people, it really is an individual experience and that is why there is no standard of treatment available.
