Jemima, you and I are so similar. I refused to do the 'get up if I couldn't sleep ' thing too; I just couldn't accept leaving bed just IN CASE I was about to fall asleep (I never ever was).
At my worst I also could feel wonderfully drowsy around 9pm (oooooh tonight I might sleep!), even sleep on the sofa (big mistake according to sleep experts), but by 10pm I was WIDE awake. And by the time I got into bed I could not have been more wired. I wasn't ever going to sleep because clearly as bedtime approached a stress hormone released in my brain. I could take 10mg of zolpidem and it still couldn't beat my crazed, frantic wakefulness. Major fear of bedtime...
You have also decided that you get one ok night followed by one bad one...so you are making sure that happens now. I bet you have full on panic on the expected bad night. You are so sure that unless you are destroyed with exhaustion, then your brain won't let you sleep. So it won't.
As I mentioned above I am taking 10mg of escitalopram (in the morning) and have been for about a month (as well as hormone treatment, which I describe in another current live thread called PND, therapy and medication). My sleep and anxiety is much improved (and certainly no depression), but I still have some residual side effects like daytime fatigue which I hope will pass. I do not know the drug you are taking, I suspect it is in the same family as amitriptyline...the latter did not work for me, neither did trazadone (another of the older antidepressants used for insomnia). I felt groggy but this didn't turn into actual sleep. It was like my phobia was too powerful for the drug to beat me. There IS a drug out there that will be more powerful than you, and you will find it.
I think only two things....
- However long you have been advised to try the dosulepine for, you should do...at the 75mg or whatever is the maximum you have been advised to take. Don't pussy around with smaller doses, take the max you are allowed. Give it a full month on the maximum dose.
- What works for one person, will be different for the next. It doesn't really matter what works for all of us, what matters is what works for you. If dosulepin turns out to be wrong for you then it is hard for me not to urge you to suffer through the side effects of trying a really good SSRI ( but probably just because it works for me, and you are not me...so I'm not trying to advise you, just sharing my experience). When I had insomnia before pregnancy I found venlafaxine absolutely excellent. I know you want to avoid an SSRI due to side effects and lack of sex drive, but I am willing to bet you aren't hanging from the chandeliers right now either. FWIW a month into escitalopram and I have only experienced minor libido decrease and can still orgasm. Frankly the sleep more than makes up for this for now, and my new good mood has made me rather more, ahem, generous in that department.
You have been suffering since Christmas, so for about 3 months? As you are about 2 weeks into dosulepine already, I predict it will take no more than 4 weeks to reach proper effects if you take full and proper dose. That is a third of the time you have been suffering for, really not long.
What do you think?
