<<Disclaimer: Verify this information before applying it to your situation.>> Six people reported taking Sonata with NO gluten reactions. Most, however, said Sonata did not work well for them. Three said instead they switched to Ambien, which is also GF and doesn't give that "hungover" feeling the next day. Another suggested using herbal teas as they had heard that sleeping pills can be addictive. FYI, per the literature that comes with the prescription, Sonata should not be taken for more than 2 weeks at a time as it can be addictive.
