Hi,
I had the same problem, they did sleep studies which were of no help. My doctor put me on Lorazapam which is great as I take it at 7:30 in the evening. I go to bed at 9 and sleep great. Before, I was at the point I was only sleepin g 2-3 hours at night. I tried to cut back to 1 pill at night but only sleep with the 2 at night. Hope this helps. It is worth a try so you get the sleep you need
