To @Natalia: No, such a change in the time of taking the pills does not matter. It is important that you always use the medicine at about the same time of the day, i.e. in your case - always in the morning.

Will taking the pill every day at 10 and during a week's leave at 11 (time Polish 10) affect contraception?

Exactly yes - you do not have to use an additional method of contraception. However, remember to use the medicine at the same time every day. Enjoy your holiday :)

Does this mean that I do not need to use additional security?

True, protection will be preserved. If less than 24 hours have passed since you missed a tablet, protection against pregnancy is not reduced. Take the tablet as soon as you remember and then take the next tablets at the usual time. So you have no reason to worry. As for alcohol - it does not reduce the effectiveness of oral contraception unless its consumption leads to vomiting within 5 hours of taking the drug. Also, do not use alcohol as a drink to sip tablets. Besides, don't worry, you are still protected against pregnancy.
