Not necessarily to the extent that you describe, but I do have hypomanic episodes that are followed and preceded by mildly depressive episodes. Both hypomania and hypodepression tend to take about two weeks. During my manic periods I don't talk to people about the things that are on my mind, but I tend to read and write lots and lots, and then attempt to organize the information. Unfortunately most of it is undone during my depressive periods.
