Laura - with me I do get a bit tired, but it takes about 4 hours. The biggest thing though is that once I'm asleep I'll stay asleep for about 11 or 12 hours, whereas before I couldn't fall asleep easily at all before 4am (now I regularly sleep at 12 or 1) and I would wake up constantly if I went to bed earlier than about 3am. So my sleep is better but mood is terrible.

Laura if you read this do you take anything for your insomnia now? I'll be disappointed to get bad sleep back when I give up mirtazipine
