depression
"I had insomnia because of my chronic fatigue syndrome and depression combined. So I had not slept properly for about a year couldn't get to sleep until 4am even when going to bed at 9 pm then when finally dosing I had vivid horrible dreams slept lightly and woke up between 3-10 times a night. This went on for a year so I was completely sleep deprived. When I was hospitalized for my depression they changed my melatonin to mirtazipine now I sleep like a baby and its great! Only side effects I had was increased appetite so I put on half a stone, but managed to lose it within two months as I had energy for the first time in a year to use the gym! Id recommend it to anyone it really works!!! iI've been on 30mg for about 5 months now."
