I have extreme anxiety. Use diazapam (10 mg) and have done so for 45 years. Also take Zoloft (200 mg) per day and Zolpidem (10 mg) for sleep. All day long I am light headed and feel like I am on a boat, rocking back and forth. Anyone have or had any of these symptoms? I also have Cervical Stenosis with Myelopathy. Maybe that is the cause?
