insomnia
"Be careful. I was prescribed Circadin by my psychiatrist to help with insomnia caused by my antidepressant. Over a period of around 3 months I became anxious, agitated, and extremely depressed. I felt like I was losing my mind. I then realised that my deterioration coincided with starting the melatonin so I stopped it. Within 24 hours by depression was under control and I was back to my normal self. It says on the drug information that it can worsen depression and cause mood changes yet my psychiatrist thought it would be a good idea to prescribe it for someone with severe depression. It also caused awful trapped wind and tummy pain. It's a shame because as a sleeping tablet it did actually work. Back to zopiclone for me!"
