If you get a DUI, your ability to drink alcohol will be severely limited.
First off, if it is deemed necessary, you will be put on Antabuse or something similar. Have fun having a drink with that shit in you.
Next, it is probable that you will have to take random urine and/or breath analysis. You are given a phone number, a color, and a state. You call the phone number every day and if the recorded message names your color, you go take a UA. If the message names your state, you go take a breath test. Failure at either of these results means you go back to square one and probably have additional fines, court costs, etc since you are likely violating probation. Not only that, but the breath tests are easily fooled and will give a false positive for even having a smoothie with no booze in it.
While it might make some sense to give someone a choice between the privilege to drive or the privilege to drink booze, in reality they will simply take away both and make it as difficult as possible for you to want to do either for the next 2-5 years.
