Eligibility criteria:

        Inclusion Criteria:

          1. Primary insomnia male or female subjects according to DSM-IV criteria (307.42) ,

          2. Sleep latency of > 30 minutes and total sleep time < 6 hrs based on Sleep History
             Questionnaire (SHQ) and verified by the inclusion + habituation night PSG,

          3. Men or women 18 to 65 years inclusive,

          4. Women of childbearing potential must have a negative pregnancy test at the screening
             visit, on Day 1 of each treatment period, and use a reliable method of contraception
             during the entire study duration and for at least 3 months after study drug intake.
             Reliable methods of contraception are:

               -  Double barrier type devices (e.g., male or female condom, diaphragm,
                  contraceptive sponge) only in combination with a spermicide.

               -  Intra-uterine devices in combination with a spermicide. Abstention, rhythm
                  method, and contraception by the partner alone are not acceptable methods of
                  contraception. Women not of childbearing potential are defined as postmenopausal
                  (i.e., amenorrhea for at least 1 year), or surgically or naturally sterile.

          5. Subjects must be in good health as determined by their medical history, physical
             examination, ECG, vital signs, standard EEG, serum biochemistry, haematology and
             urinalysis. A subject with clinical abnormality may be included only if the
             investigator or his designee considers that the abnormality will not introduce
             additional risk factor for the subject's health, or interfere with the study
             objectives,

             prior to screening,

          8. Subjects who have not been using any other non-psychotropic treatments for the past 2
             weeks or more prior to Screening with the exception of occasional paracetamol intake
