Given this formula's GABA and Valerian Root content, combining it with alcohol is worth a direct, standalone caution.
GABA and Valerian Root both relate to calming nervous system activity — combining either with alcohol, which has its own sedative effect, could amplify drowsiness or impairment beyond what either produces alone.
Avoid combining alcohol with this formula, particularly before driving or operating machinery, and talk to your doctor if you have questions about your specific situation.
