Sleep still take K

I have not found the courage to quit

K  .5 mg before bed. With this I sleep

6 to 7 hr per night.

I have anxious days so I like to sleep at night.

I may try to taper this down.

If you decide to taper there are folks here to support you.  Just remember, go as slowly as you need to.  Lots of strategies for tapering are available. 

Best of luck.
