ahhhhhhhh sleep rhythm, how I miss thee.
Do you need to take it a few hours in advance of needing to go to sleep or something?
I could really use something to do that, I stay awake for a few days at a time and then sleep for about 14 hours straight, then up for 8 hours, then another 12, then awake for a few more days, and that is the cycle basically.
It is affecting my sanity.
It's an anti anxiety drug that calms you to the point where once you fall asleep you tend to sleep longer. It will make you drousy, but as a sleep tablet per se it's pretty hopeless.
It's more used in clubbing circles to take the anxiety out of the comedown, as pot does.
There are far more effective sleeping tablets, but it can help set sleep patterns in some cases. Usually an hour before sleep is best.
I last took some when I flew. It's great for economy flights, a) because it relaxes you to the point where you dont care too much about anything and b) because it's a muscle relaxant and it means the seats are more comfortable on long flights.
However you do tend to doze off during films, but with on demand movies in long haul economy thats not much of an issue.
Oh alcohol increases its effect. Vallium is rather interesting with red wine. That combo and you will sleep!
