For sleep I definitely prefer Flurazepam....works great always! But I have anxiety issues as well, occasionally, and my new doctor will not prescribe Lorazepam and Flurazepam....so I opted for the Lorazepam. Because it helps both issues. I take an over the counter with the Lorazepam, so that helps. And you can break them in half so you can take half at bedtime and half in the middle of the night.....I do that so I sleep longer into the morning.
