This must be getting you down Kari. Are you seeing anyone about it?
Sleeping pills have a short half life in the body so, after taking them, you have about half hour to an hour for them to start making you drowsy. You need to get to bed then.
If you stay up you will get past the effective period of the medication. Also alcohol will act as a stimulant and help you overcome the effect of the tablets.
I'm a long term sufferer and the only way to do it is to be strict with yourself, go to bed and remove all stimuli-no music, tv or pc- although a little reading sometimes helps.
On a lighter note I see there's a Finnish people group and I also found a sweet thread where people petition John to change their user name.
A load of us could change our names to Finnish common names and the group would be huge
Or you could just have a "Friends of Finland" subgroup
