Replying to Post Concussion Syndrome

About a month ago I knocked myself out skiing and ended up with a pretty bad concussion. That night I started vomiting and went to the ER where they did a CT scan. It came back fine, but I am still experiencing headaches and mental fog. Last week i went to my doctor who said I had post concusion syndrome and that it could take anywhere from weeks to months to years to go away. Has anyone else had post concusion syndrome? Any advice on coping with the symptoms?
