Panic Disorder and Agoraphobia were both rated. I started taking Nardil two years ago after developing agoraphobia while living in Asia. In about a week, it helped to halt the anxiety episodes and phobias. I've been taking it for over 15 years with no serious side effects—just some weight gain that is manageable. It's also very effective in reducing symptoms of Parkinson's Disease and Restless Leg Syndrome. Nardil works by blocking excessive amounts of dopamine inside the brain. This decreases your body's need for the hormone serotonin. Serotonin is responsible for many mood-related feelings such as happiness, sadness, anger, fear, and pain. When you stop taking Nardil, your body will eventually make more serotonin so these feelings will return along with any other side effects you may have experienced. Anxiety disorders are frequent among those who suffer from Panic Disorder or Agoraphobia. These conditions can be diagnosed if you experience three consecutive months of intense anxiety or panic attacks. Anxiety disorders can also occur without having any apparent cause; this is called "pure anxiety". Panic Disorder, for example, is characterized by repeated episodes of sudden feelings of terror known as panics. The person suffering from this disorder cannot control these feelings and they lead to significant damage due to the inability to perform daily tasks. Anxiety disorders are very common - one in five people will experience an anxiety disorder at some point in their life. They often begin during young adulthood and are twice as likely to affect women as men.
