There's actually 3 drugs, and they're all of the same drug family apparently, and I've tried all three. I don't remember the names of two of them, I'll have to think about it more, but the one is marketed as Lunesta (lunesta.com) in the USA. Sorry I guess I sort of lied about the side effects part, apparently there can be side effects, but they are quite uncommon. Most people experience no side effects, so I was told. I know I didn't have any side effects on any of the three drugs I tried, and that's quite telling for me as I usually react quite strongly to all drugs. Except I believe the one caused me to have a bitter taste in my mouth for about an hour after getting up in the morning, the first couple of days I took it. But I didn't have grogginess or headaches or weird dreams and so on. I slept for 8-9 hours straight each night I took a pill, but I felt awake when I got up in the morning, it wasn't so difficult to wake up as it is on other drugs. I had no withdrawals when I had go off them. These drugs are apparently non-habit forming. Anyways hope that helps. I'll try to remember the names of the other two but your doctor might know if you say they are related to Lunesta.
