insomnia
"I have been using this medication on and off for 2 years. I found it very useful for anxiety and insomnia, but yes unfortunately all the atypical antipsychotics have the terrible side effect on most people of weight gain in my case 3.5 stone - that's 49 pounds, but I was taking 400mg at the time. It seems to affect women much more, I was so fat around the belly people thought I was pregnant! But I was very ill with chronic unremitting anxiety and insomnia, so was relieved to find something which finally worked.  Now if I need it, I occasionally take 25mg but it does take about 45mins to fully kick in. The worst thing about it though is it slowly paralyzes your thoughts as it's working and if you read like me in bed it can be quite weird."
