Hi sir Good afternoon I can understand your concerns regarding addiction with Benzodiazepines First ...u should search for the cause of insomnia. Example...insomnia one of the common symptom for somany psychiatric disorders like depression , generalized anxiety disorder,  panic disorder and medical disorders like thyroid abnormalities...soon . If we solve the main disorder then automatically....ur sleep disturbances will ne corrected Regarding  benzodiazepines...they become addictive if used more than 2-3 months. As u said...u used it for 2wks....it can be stopped.no problem. But...ur sleep problem may be returned back as ur main reason for sleep issue not resolved So...I advise u to consult a psychiatrist for proper assessment and treatment
