Getting worse??

I have been taking Stilnox since late Feb.. stopped for a few weeks during May/June I guess..
but taking it again now..

First I took 10mg as my doctor suggested for quite awhile then I dropped it to 5mg then even 2.5mg.. it always work.. at least for 4 hours.

I started taking Stilnox again recently and I'm taking 5mg only and it works as usual until this week. I just felt sleepy but couldn't sleep with 5mg.. and had to take another 5mg.. which made me a bit scared.

Don't really know what I could do to stop it but Stilnox is not addictive so it should be my own problem.. should find out the problem as soon as possible... sigh

I don't want to be the next one who do those stupid sleep-driving, sleep-whatever thing..
