I've struggled with insomnia for most of my life. I think it goes back to the abuse I endured as a child by my step dad at night, when my mom was working; I remember being afraid to go to sleep as a kid. Mirtazapine (Remeron) has helped me sleep (as well as worked for my depression) but has caused weight gain. Doxepin has also helped but I needed to take 30-40 mg, a higher dose than some people take for sleep. The higher doses (50 mg and up) are also prescribed for depression. So for me, sedating meds, not necessarily hypnotics like Ambien have worked best. Hope you're able to get some sleep!
