My experience is that is aids in both. I sleep longer during the night. I used to getwake up or get up two or three times, and now it's once. Sometimes not at all.
Hi-- I found I slept deeply and straight thru. Got to sleep very quickly. I am not a chronic insomniac, thank god, but found this helps quite a bit. Could not WAIT for it to get back into stock. Now I have used it a week, and have slept straight thru, a very peaceful, restful, fulfilling and wonderfully needed sleep each and every night.
