Maybe try doing some heavy activity before bed. Go jogging, lift weights, wear your body out. Then, go eat something very heavy, brush your teeth, and hopefully pass out and get a good nights rest.
This will do the opposite I am afraid.
Ensure if you eat late its light and easily digestable.
No lights of any kind ,standby light alarm PC light ,hall light ,mobile fone screensavers, black as hell.
Externally that's all you can do.
Drug wise and excluding booze and benzo there's the 2 Z-class drugs
Zolpidem I used to use but I only needed help getting to sleep then ,when I moved country it was to dear so I swopped to 2mg lorazapam did but its a benzo. ... and to be honest I started just eating them all day. Zolpidem I did not abuse.
Zopiclone the big brother will work all night but usually into the next morning and with most people makes your mouth taste like utter crap. Metallic and veryalmost hangover and it never seems to stop after time ,way worse than trazodone.
The 2 anti-d Mirtazapine is know for the sleep properties you have mentioned andin some extreme weight gain and craving for simple carbs ,long haflife too if you miss a dose or two .
Trazodone the much older one is now rarely if ever prescribed as a anti-d, it made me feel knock out before bed but nicely ,not lik zolpiclone but I take ritalin in the morning and jog so if I am tired I see it as tough shit ,do it.
I've been on and off -good times/bad times in my life mirtazapine for over 10yrs from my lowest dose 15mg now [cost] to the max dose [UK] of 45mg and I did find it incredibly nicely stimulating in a 'non-wired' way .
If you are sleeping too much take it 2hrs before bed without being in bed or doing anything too brain draining. If you feel too 'heavy' in the morning it should ease up or just hit some caffeine pills/expresso's.
I'm surprised it was given to you just as a sleep aid as its a very powerful anti-d so if you ever feel able to stop mirtazapine it does come in 7.5mg breakable tab so you can taper.
Exercise as said done early before the evening will help in more ways that one, morning cardio on a empty stomach -even just a 20min walk with some music is great or just silence if you live near any parks or countryside.
Good thing about mirtazapaine is it won't blow out on you or require upping the dose or a 2nd med.
Obviously your overall mental and physical health/diet play a huge part in sleep and more important your sleep cycles.
Lastly [since I live by the clock] set your alarm for bedtime as well as waking up so its all uniform, even weekends,try to sleep and wake up the same time everyday no matter how tired you feel and take your pill the same time ,your body loves routine.
If you are you are young you will need-want more ,as you get older 6 hours isn't so bad and usually it's all the time modern life gives you.....well me anyhow but I force myselfto get up and jog for 30mins at 4.30 no matter the weather of how tired I feel ,you get used to it;
Also....some people can sleep soundly with their TV on and even volume up ,don't try cause because what you watch unless its your own copies of a series then it will end varying times.
Ole skool- read a book......it will make you feel tired very quicky and don't sit up playing with or checking your phone for message, put it on silent ,not vibrate and read your silly long posts like this one on your laptop in bed ;-) .
Best of luck......I know after even 2 days you start to go abit crazy ,it's torture hence my drivelling reply ,I know how bad it is.
Lastly find a nympho. That always works +in the end you just makes a excuse not to do it again and say you are going to sleep. Winwin.
.....and re -enforcing the point from my soapbox of hypocrisy stay ckear of the benzos and z-class if poss.
Mirtazapine will rapidly calm anxiety too so if you are unwittingly worrying about useless crap before bed it'l chill that right out ,should feel it working once you know what you are looking for after 15-20min.
Just watch your weight.
