I have all the above symptoms and have started a low dose of amytryptaline recommended by psych for the above symptoms. It has definitely helped so far alrhough I still have off days but more good then bad. I did not get any side effects from the amytryptaline, it helps me sleep at night and helps me with my headaches as well. Amytryptaline has many uses but one is for this off balance rocking floating sensation. Just wanted to offer something that has helped me.
