You do not say what is causing the dizzines and feeling out of it? Are you on meds, if so you may need to talk with your physician about your meds.
I would definitely not advice driving if your dizzy and "out of It" that is not only a danger to you but to others on the highway.
Do you have a therapist to talk out your issues with?
