Thanks for using health care magic for posting your query.
I have gone through your given history in detail.
In your description you have stated that your wife has a psychiatric problem. However you have not stated what kind of psychiatric problem. Secondly restyl which you have given is useful only for sleep disturbances and in anxiety
and no other disorder.
It will difficult to identify what is the reason you wife is not having sex with you without visiting the doctor.
Do try to convince her to see a psychologist/psychiatrist
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.

Wish you good health,
Dr. Srikanth Reddy M.D.
