Not sleeping or eating on mirtazapine

Hi there.  I have been prescribed mirtazapine for severe anxiety and insomnia but it is having no effect whatsoever. Has anyone else experienced this?

they say that the lower dosages work better for sleep, I also take 10 mg of melatonin with the med, I was o15 for 2 weeks and 7.5 for 6weeks, took awhile to get my sleep back maybe like 2 weeks or so, I don't think higher doses work as well for sleep, I have anxiety also.

How long have you been taking it, I found after about six weeks I was sleeping really well and have a big appetite which is good, but still have anxiety, not so bad but still have to take propranolol.

It never worked for me neither at lower doses (which strangely is supposed to be more sedative) . The only drugs that put me to sleep quickly are Zopiclone or Zolpidem. But docs are wary of giving them out. A few strong alcoholic drinks also does the trick but drinking too often can cause depression or make existing depression worse.
