depression
"I was taken off Citalopram after a relapse into depression due to bereavement issues and put on to Sertraline, initially 50mg/daily.
This didn't work and so, on my GP's advice, my daily dose was increased to 75mg. This dose has also proved ineffective but, worse than that, it has triggered severe insomnia. As I write this, I have been awake for 22 hours straight and still don't feel like sleeping. I have also lost my appetite.
I have taken many medications throughout my life (I am 56) but Sertraline is the only one where I have experienced any side-effects. I would be wary about taking this medicine."
