Best non prescription sleep aide
 February 17, 2013
"I work for an airline and travel worldwide. Between menopause, jet- lag, sheer exhaustion, this is the supreme, non addicting, natural sleep aid I have ever tried....after 30 yrs I have tried everything and don't want to dependent on any drug. Tryptophan works wonders and I especially endorse Source Naturals even if they are pricier. sweet dreams!"
