Dysphoric Milk Ejection Reflex (D-MER) is an abrupt emotional "drop" that occurs 
in some women just before milk release and continues for not more than a few 
minutes. The brief negative feelings range in severity from wistfulness to 
self-loathing, and appear to have a physiological cause. The authors suggest 
that an abrupt drop in dopamine may occur when milk release is triggered, 
resulting in a real or relative brief dopamine deficit for affected women. 
Clinicians can support women with D-MER in several ways; often, simply knowing 
that it is a recognized phenomenon makes the condition tolerable. Further study 
is needed.
