Yes, check this out. There's lots of discussion about insomnia on this SR website. Lots of approaches. Check with the doctor, but beware of prescriptions which have multiple refills or prescriptions in large amounts. Always make sure that your doc has control over the way you take your meds. It gets better as you go along. Maybe use TV to distract yourself at the beginning. Exercise, reading. Keep occupied. Your body is going to try to get you to resume drinking. Listen to that little voice within and then say "Get back in your cage, you bad dog! I'm not going to follow any of your suggestions any more. You've been nothing but bad news for me. So don't try to convince me that I'm "all right" and "one little drink won't do any harm." Put that beast back in the cage and throw away the key.
