Ideas:

• Make sure you are getting the B-vitamins your nervous system needs. Molecular Multi is a good place to start. Or, if you already have a multivitamin/mineral you like, add Nerve Guardian.
• Make sure you are getting enough magnesium.
• Read this Library page about stress.
• Listen to a good People’s Pharmacy radio interview about anxiety.
• Try the app program recommended in that interview, Unwinding anxiety.
