I strongly believe that a person who wants to achieve proficiency in public speaking can not ignore the use of alcoholic drinks.

The bad news is that this year Ukrainian Parliament passed a law which gives the right to local authority to ban selling alcoholic drinks in the nighttime. The reason for such law was care about public health and security. This rule entered into force in Kyiv one month ago. And now we are limited to polish public speaking skills after 11 pm till 10 am.
See my speech about new order.
