I was told not to take the time released. I take 3mg sublingual and am able to sleep through the night and wake up feeling like I have slept. My dr said that I can take up to 12mg a night if I needed it. So far it is just the 3, but it is nice to know that if I wake up I can take more to go back to sleep. I would definately check with your dr about it, because it can interact with other meds.
