As Kathy already states, is it the pills, or is it the fact that the people with insomnia have other conditions that may be the cause? Thinks are not always cut and dried.
I have had awful insomnia at time. Fot months at a time sometimes. I would guess people with little sleep are at risk for a lot of things like not seeing a red light and hitting someone or getting hit, doing something foolish at work cause your so tired you cant think strait and so on. Then I am sure there are directly linked health issues from a lack of sleep like a stroke maybe or seizures or god only knows what. When you are working with little sleep for long periods of time things go wacky with your body as well and mind.
I hate taking pills but I finally asked my doctor for something cause I absolutely hate tylenol PM and they did not work well anyway. The next day I would yawn all day and be tired as heck. He prescribed ambien and it works great. If I cant sleep I take a half a pill and it works. You need four to five hours of sleep at least to take one. So I wait until I have only a little over five hours of sleep time left before I have to get up before I bite the bullet ant take one. It is a godsend. For me there is no after effect when I wake up. I have taken about 20 or so since I have had them for a year and a half or so. So that would be 40 times I guess. It actually helps I think because I know i have them and that I will be able to sleep if cant fall asleep. So knowing that, I think I can fall asleep easier when I have trouble falling asleep, if that makes any sense, which for most folks out there who suffer from insomnia I think it will.
So until they can say, its the pill that is killing people, I will take them, cause four hours of sleep is better than 0 sleep and going to work or having to call in and use vacation and then worry about money which causes more insomna, which causes more money issues which causes more insomnia.................................
