I made a fairly extensive list of hypnotics I have experience with in another thread, I'll copy+paste it here:
ZOPICLONE - Helped me fall asleep, woke up abruptly with in 2-3 hours feeling really weird. On the third day I had to up the dosage, which caused delirium and realistic hallucinations. Also left a rusty metallic taste in my mouth for the next day, which made eating anything quite unpleasant.
ZOLPIDEM - Essentially the same as zopiclone, although tolerance took a little longer to build up, there was no funky taste, and the delirium was worse and quite terrifying.
MIRTAZAPINE - Didn't work at first, started working for a while, but soon lost efficacy. Also, if I didn't use my usual nightly scheme of recreational drugs (cannabis, small amounts of alcohol sometimes) which coincidentally helps with sleep, I found mirtazapine to help very little.
QUETIAPINE - Knocks me the fuck out, but with nasty residual side-effects the next day. This would be one of my very last resorts on this list, despite being probably the most efficient.
OXAZEPAM - Takes forever to start working, and is quite mild, so I had to eat tons. No residual hangover, but sometimes I'd almost wake up an hour or two earlier than I'd prefer - depends on how long I have to sleep.
DIAZEPAM - Slight residual grogginess - works quite well, but I have to take larger doses than more specifically hypnotic drugs.
TEMAZEPAM - This was the first one I was actually satisfied with as a whole - sedating and hypnotic at low (ie. the prescribed, recommended starting therapeutic) doses. Works for the right amount of time for me not to be sedating in the morning.
NITRAZEPAM - The most sedating and hypnotic benzo I've tried. Works for real long, though, so either make sure you've got time to get yourself straight in the morning or take it a few hours before bed - if you've got shit to do in the morning.
LORMETAZEPAM - Like temazepam, but works a little longer, and is much more anxiolytic - like lorazepam. It's pretty much halfway between those, if you ask me. I found this to be an effective hypnotic.
FLURAZEPAM - This was not particularly sedating physically, but helped me fall asleep as soon as I hit the hay, and was very relaxing. Produces a very long-lasting active metabolite which I did not find at all unpleasant in the following day or two, as it wasn't too sedative - merely anxiolytic. Careful with the doses, though, or it could turn into a long blackout or at least a few days of grogginess and impaired efficiency at work/school/whatever.
I would like to add that Midazolam may also work, but it only helps you fall asleep, not stay asleep, owing to its short duration. Flunitrazepam is the strongest, most hypnotic benzo I've tried, but it's quite amnesic and has strong residual 'hangover' effects.
