Sorry you're still struggling to get sleep.
I like Lunesta much better than Ambien, but that's what works for me. Everyone's different.
Also, have you every tried accupunture? I've been feeling awful lately & my insurance will only cover sleeping meds 2 months out of every 3. So strange. Apparently it's because Lunesta is so much more expensive than generic Ambien. I've tried other meds, but I like Lunesta the best. That said, there are a lot -- a LOT -- of meds used to treat sleeping disorders out there. But since it's not fool-proof & there are these in-between times with no insurance coverage where I get a decent amount of benefit from accupuncture. Plus, the temperature of your bedroom really does make a huge difference, I've found.
As far as what the options are: I think the most common ones are Ambien, Lunesta, Rozerem for hypnotics, Remeron, Ativan & Valium for anti-anxiety meds, Seroquel for anti-psychotic meds, Neurontin & Lyrica for anti-convulsant meds & a whole bunch of possibilities for anti-depressant meds. Sleep is so elusive. If your psych doesn't want to try different things to get you some more sleep, maybe try a sleep specialist. Usually they are either prescribing psychologists or neurologists who can take a history & list of symptoms from you, run any tests needed, provide some advice & set you up with different meds.
I do know that sometimes meds intended for one thing end up having the opposite effect. So confusing, but pretty much any psychoactive drug can be tricky to work with. When I'm not on Lunesta, the most effective med for me is Soma (a muscle relaxant). It doesn't really do much of anything to help my muscles relax, but a side effect is to make people sleepy & it definitely makes me sleepy. :) At my last visit, my doc even suggested Marinol. I'm not willing to try it since I'm looking for a job right now, but it is FDA approved and completely legal under federal law in the U.S. Some people swear by it -- puts them to sleep for 9 hours they say.
But, really, navigating the myriad of meds that can be used for sleeping is pretty much impossible without an expert. A psychiatrist or neurologist (or at least a prescribing psychologist who specializes in sleep disorders) can help figure out which ones are safe for you to try with your medical history, symptoms & other medications.
Also, a lot of people are helped by keeping the bedroom just for sleeping & spouses. If you are staying in bed too much tossing & turning -- or reading, or writing out to-do lists, or worrying, etc., your brain starts to associate your bed with not sleeping. Some people are helped by getting out of bed when they can't sleep -- read, watch tv, do something relaxing (whatever that is for you) -- and then when you start to feel sleepy again, go back to bed. It sucks for the first few nights because sometimes you spend more time out of bed than in it, but after that (assuming you don't have an underlying neurological disorder), people start to sleep longer & longer.
