"i have had trouble sleeping for about 4 years after a breakdown i currently take an antidepressant and did have zopiclone to help me sleep which worked really well and gave me a good nights restfull sleep , my gp discontinued the zopiclone a year ago and my nights are terrible i can lay here for hours and my head won&#039;t turn off and will usually end up getting about 2 hours sleep. i have recently been given temazepam 10mg which does not work at all. i have doubled my dose to 20mg but still no luck with sleep, hence i&#039;m writing this now at 2.18 am. i have been trying to look up to see if they clash with my anti depressant venlafaxine ."
