I do one of several things depending on why I have writer's block. If it is in a current story, I go for a walk with my husband. We talk all the way while we are walking. By the time I get home I usually have several ways I could go with my story. If it is because I am between projects, I sit at my computer and write down anything that comes to my mind. Sometimes it makes sense, and sometimes not, but at least I can say I wrote. Often some kernel of it is the start of a new story.
