Hi Subie, yes I have been suffering with this for way to long. The Ambien has given me some good years, but unfortunately all good things must come to an end. You mention feelings towards night coming, ABSOLUTELY. Night time is not my friend, and when I haven't slept much I almost start to become obsessed in the early afternoon with night coming. When the sun starts actually going down is when all the anxiety and depression hits all over again. I don't want to live this way, and I am so envious of the people that can actually be asleep 5 minutes after their head hits the pillow. I have never had that feeling. I've been in numerous insomnia and sleep forums through out the years, and what the people have said about the sleep clinics is that you pay them thousands of dollars to hook you up to all these wires, watch you sleep or not sleep, then in the morning they verify that yes in fact you do have insomnia or apnea or whatever else you already knew you had, and they send you home. Nothing is ever accomplished for you the patient, but because alot of us are so desperate we will try anything, the sleep clinics have just made more money, and we are still left with the same problem. I also have been to psychiatrists, but I do have to say that a couple of them were really pretty good, I now know of two things that have more than likely contributed to my insomnia, but knowing that, has unfortunately not helped me sleep. I think at this point my best bet is a sleep therapist, or maybe at this point my last ditch effort is a sleep therapist. Thanks for your words
