Hi,
I am also interested in anyone who has had a relapse. There is one researcher in my home town who believes that PP is a first episode of bipolar disorder. That said - My doctor says that I am definately not bipolar. So it is really hard to understand who is right. Here is some info on bipolar and also information on sleep deprivation and PP. The researcher's name is Sharma and he is from London Ontario. You can google more articles on him. Here is what he says.

Causes and Risk Factors of Postpartum Psychosis
Although more studies are needed to determine the causes of postpartum illnesses, the evidence suggests that the sudden drop in estrogen levels that occurs immediately after the birth of a child plays a significant role, along with sleep disruptions that are inevitable before and after the birth. Many researchers conclude that postpartum psychosis is strongly related to the bipolar spectrum. Indeed, one theory is that new mothers who have psychotic episodes and dramatic mood swings are actually experiencing their first bipolar episodes, with the manic-depressive illness having been "dormant" beforehand and triggered by childbirth. In fact, for 25% of women who have bipolar disorder, the condition began with a postpartum episode (Sharma and Mazmanian).

Abstract
Postpartum psychosis is a rare but severe psychiatric disorder. Its diagnostic status remains controversial, but several studies have shown that the majority of patients who develop psychosis immediately following childbirth suffer from bipolar disorder. The pathophysiology of postpartum psychosis is poorly understood, but factors such as primiparity, difficult labor, genetic predisposition, and hormonal changes have been suggested as etiological factors. This paper reviews the literature on the relationship of sleep disruption and postpartum psychosis. It is argued that sleep loss resulting from the interaction of various putative causal factors may be the final common pathway in the development of psychosis in susceptible women. Clinical significance of these findings, including strategies to prevent postpartum psychosis, are discussed and suggestions are made for future research directions.
