Over the last few months I have found it harder and harder to drive. I have had my license for over three and a half years I have never had any problems driving. About 6 months after I got my license I notice I would start to feel dizzy and unbalanced driving on the freeway or on mountain roads and overpasses. I used to be able to shrug it off. Last winter I finally began to find it impossible to drive on the highway for any time longer than a few minutes. Then I find it hard to wait at stoplights. Now I basically don't drive anywhere except on the empty back roads around where I grew up. I am confined to hitching rides, walking or taking the bus and its hard for me to get anywhere.
