Yeah i dont take mine, which sucks because i actually enjoyed them as i cant fall asleep if i dont use them. Anyways had this whole heart rate thing and had to stop using them so looked into some alternative routes. Found some topics on doctors using cannibus for younger patients in califonia. I wasnt a user ever before but have found it helpful especially in slowing my mind down enough to focus on one thought, and the sleepless nights are gone as well. If you live in a medical state look into it.
