"i&#039;m in uk. i&#039;ve taken mirtazapine for 3 nights &amp; so far it has had no effect on my insomnia. it has perhaps made it worse as 2 of those nights i couldn&#039;t lie still but was fidgety &amp; restless. i end up taking a temazepam, otherwise i literally lie wide awake all night.  but i can&#039;t do this indefinitely as docs at my practice just refuse to give scrips for temazepam &amp; other benzodiazepines, even though i have never abused these drugs. 
i don&#039;t want to lower the dose as main reason for taking mirtazipine is my chronic anxiety, which i&#039;m still hoping this med will help. 
apart from the restlessness at night there have so far been no side effects. felt a bit spaced out yesterday but nothing serious. 
but wish could night get good nights sleep."
