I consider this one of the most powerful methods for eliminating Panic Attacks and General Anxiety out there.  Here are some common Panic Attacks Symptoms, and tips on how to prevent Panic Attacks.  

Panic Attacks Symptoms appear suddenly, without any apparent cause. They may include

• racing or pounding heartbeat (palpitations); 
• chest pains; 
• stomach upset; 
• dizziness, lightheadedness, nausea; 
• difficulty breathing, a sense of feeling smothered; 
• tingling or numbness in the hands; 
• hot flashes or chills; 
• dreamlike sensations or perceptual distortions; 
• terror: a sense that something unimaginably horrible is about to occur and one is powerless to prevent it; 
• a need to escape; 
• fear of losing control and doing something embarrassing; and 
• fear of dying. 

A panic attack typically lasts for several minutes, is one of the most distressing conditions that a person can experience, and its symptoms can closely mimic those of a heart attack. Typically, most people who have one attack will have others, and when someone has repeated attacks with no other apparent physical or emotional cause, or feels severe anxiety about having another attack, he or she is said to have panic disorder. A number of other emotional problems can have panic attacks as a symptom. Some of these illnesses include post traumatic stress disorder (PTSD), schizophrenia, and intoxication or withdrawal from certain drugs of abuse .

Anxiety attacks that take place while sleeping, also called nocturnal panic attacks, occur less often than do panic attacks during the daytime, but affect about 40%-70% of those who suffer from daytime panic attacks. Nocturnal panic attacks tend to cause sufferers to wake suddenly from sleep in a state of sudden anxiety for no apparent reason and can have all the other symptoms of a panic attack. The duration of nocturnal panic attacks tends to be less than 10 minutes, but it can take much longer to fully calm down for those who experience them.
