insomnia
"I have been using Mirtazapine for over 10 years, I started with a does of 15mg which worked wonderful with insomnia, however during the time of first using it I was suffering from anxiety, and my doctor up the dose to 30mg which I was on for a few years, until anxiety became worse, which he up the dose to 45mg which I found was to strong as I noticed that dizziness started to happen, so I halfed the dose of 45mg and it all settled down. The dose was a little low, so I went back to 30mg and have been on this dose for the last 6 years. I do not get side effects from this medication of weight gain, or dizziness and even photo sensitive, I have been on it for quite some time and do not plan on getting off it as it works wonderful."
