If in fact you like to consume alcohol and are in the state of Texas you should take some time to learn about the public intoxication laws in force in that state. The first thing that you will realize is that if you drink so much that your acts and behavior can put the life of another person or even yourself in danger and you are found to be intoxicated you can be charged with an offense under applicable state laws.
A public place, according to Texas laws is any place that has a license or which has permission under the state's Alcoholic Beverage Code. In case you are found guilty of public intoxication under Texas laws you will, other than in the law's Subsection (e) be considered as having committed an offense that will be classified as a Class C misdemeanor.
A Class C misdemeanor is the same as when you are given a ticket for speeding on the road, but its effect on your record does look a bit worse. You can be fined up to five hundred dollars and you may even be put into jail for between four and twelve hours from the time of having committed the offense.
Under Subsection (e) the offense committed by anyone that is not twenty-one years of age will invite the same kind of punishment as would be applicable if a minor was to have committed an offense under Section 106.71 of the state's Alcoholic Beverage Code.
You can only escape punishment if you can prove that the alcohol in your blood is present because of having been administered the alcohol due to therapeutic needs and also if it is part of your medical treatment that is administered professionally and by a licensed medical practitioner.
If you don't want to be booked under Texas laws you must ensure keeping your alcohol consumption to an acceptable limit; otherwise, you will, if caught, be penalized quite severely.
