Sleeplessness

My friend is suffering from sleeplessness now.
I had been in such a situation about 10 years ago, too. So, I can understand his suffering. It had given me hard ache both mentally and physically. And, escape from the situation is very difficult. For me, changing job was the effective provision. But, changing job is also difficult now.
I think he will be fine if he climb North Alps in this summer with me.
