question: When I got up this morning I stood up and could not take a step forward.  Every time I tried I took a couple steps back, on the second try I even backed into the night stand.  Third try again could not go forward.  I finally on the forth try was able to step forward.  What is going on.  I was not dizzy or sick to my stomach like when you have vertigo.  I have not had any other problems.Help, Linda
