I am a terribly restless sleeper prone to insomnia, made even worse by developing hyperthyroidism in the last few years. Two or three of these gummies and 20-30 minutes later, I am OUT. If I'm having a particularly rough night, I may need another one or two if I wake up later in the night, but they always work - better than some prescription medications I have tried, which kinda blows my mind. They taste is great, too! I will definitely keep these on hand
