Open Question: How long will MSG stay in your system?

After ingesting La Choy soy sauce I've experienced some symptoms of msg: rapid heartrate, chest pain, irregular heartbeat, and most noticeably insomnia. I didn't sleep until 4 am last night. I am wide awake on a Saturday morning--that's not normal! Can someone please tell me how long this stuff will stay in my system? Is there something I can do, some medicine or food I can eat that will get this horrible stuff out of my system?
