I get bad insomnia. I think the site feeds on it; you're just about to shut down and go to sleep then you read something you have to respond to.
Try drinking half a bottle of wine. Always sends me off.
Drinking can cause isomnia in the long run..
Drinking kept me awake wanting me to drink more. I kinda quit and everything went away.
Now, I feel sleepy by 11pm and feel fine.
I also make sure to clear the mind before sleep.. No bad thoughts or anger.
