Yes: Quality and accuracy of dose listed on the bottle will vary. The Rx version is higher yet! 7.5mg is ok if it works, but I sense a bad trend: if 5mg worked but stopped and you now need 7.5mg to sleep, this dose will stop working after a while. Explore non med sleep hygiene,such as no caffeinated drinks after 5pm, same bed and awake times, no naps, dark cool room, bedroom for sex/sleep only,
