Well when I take it, makes me very very tired. Which makes sense, it does lower my heart rate, I'm not running on adrenaline, and when the adrenaline stops I feel hella bad, really bad. So I can't take it in the morning. Now at first it was helping at night. I cut the smallest dose in 4th's and took 1/4th. I was sleeping better and not waking up, sleeping through the night. After awhile though I started feeling stimulated and the feeling that I hadn't slept, the non-restorativeness got much much worse. I was waking up much more sleepy so I didn't know what to do. I am extremely sensitive to medication, Dr. Rey said one of the worse she's seen in this regards. I've only seen my dys. specialist 2x's but am planning on seeing him this summer and discussing all of this with him. Certainly calming down all this adrenaline will help my sleep.
