The answer is yes, you can ask the judge if he will impose an imprisonment-only punishment, but the judge is under no obligation to do so, and could easily impose a fine instead, or even both. Judges tend to take DUI cases very seriously, and do not look to accommodate the impaired or drunk driver, so it is unlikely that the judge will take your request seriously; it is much more likely that he will follow the general sentencing guideliness given the circumstances, any prior DUIs, etc. You are urged to retain an attorney to help you--DUI can be very serious, and an experienced lawyer will greatly increase you chance of a good (or least "less bad") outcome.
