Recently, I have noticed that I want to sleep in the car. When I drive, I now have to have the windows down and the air flowing or I tend to want to drift off. (almost like being in a tunnel)

I have had no changes in my medications (Butran's, clonidine patch's, neurontin, abilify, nexium, estrogen) for over a year now so I am not sure what is going on.

Has any one else experienced anything like this?
