Insomnia?: It sounds like you're having difficulty with insomnia. There are many possible causes for this -- including drug/alcohol abuse and psychiatric illnesses such as bipolar disorder and major depressive disorder. There are also primary insomnias. If you already have a psychiatrist, please see him/her about this problem. If not, start with your primary care physician.
