I've alternated between, lorazepam 0.5 - 1.5mg, zopiclone 7.5mg and clonazepam 0.5 - 1mg. I've only taken them at night and either 3 nights in a row followed by one or two nights off, or at the very worst every second night. I've recently come off paxil(long term), and am now trying to wean off citalopram that I've been on for 6 months. My sleep is terrible and has been since I stopped paxil, hence the commencement of citalopram. I developed this wake-sleep disorder it seems, I get jolts(hypnic jerks), startle responses that seem exaggerated, and noises in my head all and only at sleep onset. Just as I am drifting off, I will get a fear response(like when someone sneaks up and scares you) and a jolt in my chest that feels like my heart tried to jump out. The thing is, I don't feel anxious before all this happens. Also I'm noticing that now I'm waking up anxious after taking a benzo and that the head noises, jolts, zaps, startle response are worse when I try to fall back asleep. I know this is complicated and I feel despaired and helpless. Why would a benzo cause me to wake up in an anxious state? I will only sleep an hour or two without the benzo, and still get the jolts, zaps etc... but without the anxiety. I'm hoping this is SSRI related, so that I can rule out benzo addiction.
