After taking big breaths in and out my entire body began to uncontrollably shake for about 30 seconds and i only remember before and after the event?

Possible seizure: This sounds like you may have had a seizure. About 10% of Americans have at least one seizure in their lives. This may never happen again or may be a sign you are developing epilepsy, which can be controlled with medicines. Seizures can lead to injuries, esp. if you are driving when it happens. It would be a good idea to see a doctor for evaluation. See http://tinyurl.com/guzq3u2 for more info.
