i bought a bottle from cvs. 60 gummies each 5 mg. my kid was having trouble sleeping and these worked like a sledghammer, it was great! also comical, knowing the dose was way too high, i would slice the pinky-fingernail-sized gummy into 10 tiny pieces. “do you want this gummy?” “can i have more?” “no” “do you still want the little piece” “yes”. so then she would try to make it last by sort of licking it or just taking it in and out of her mouth and it would get lost of forgotten- funny business. anyway, we dropped off the use of the sledgehammer precipitously as we wanted her to develop her own sleep skills and avoid any of these lesser known potentially negative effects. we still keep the (lifetime supply)tool in our back pocket for rare occasions, like traveling.
