Effects of Sertraline on sleeping pattern

I've been taking 50mg of Sertraline now for 2 weeks. Since being on the drug I've been unable to sleep properly at night yet often spend periods during the day when I do nothing but yawn. I'm worried that lack of sleep will compound the issues that Sertraline was prescribed to alleviate.

Has anyone else experienced similar side effects?

Yes my sleep pattern was bad for several weeks. Two hours max. and almost impossible to get back to sleep. After two months now back to normal.
