I have noticed after the anti-depressant kicks in my insomnia has been slowly increasing. I feel wide awake for some period and then becoming so tired and thought that I could sleep but then when the light is off and I just slowly back to becoming wide awake again. I usually unable to sleep around mid night, the usual hour that I can fall asleep will moving away from 3 am to later and later. No matter how I tried to tired myself out and go to bed at normal hour, it won't happen. Please help!
