i believe that my dr comes from a hormonal imbalance. i have endometriosis and my homones are all out of wack. i am trying to correct my imbalance with very little success. i had surgery in august and my dr has been tons better. i do still have some but i think that my ovaries are better able to produce the hormones i need with out a ton of cysts covering them. i'm pretty sure not all dp/dr is caused by trauma or drugs.
