What is it called when someone gets encouraged by people around him/her or gets pepped up by the atmosphere around to the extent that he or she gets a wrong impression about his/her powers and capabilities (physical or mental), and probably gets out of control and starts doing crazy things in an effort to do the job right.
For example, I'm looking for something similar to filling in the following sentence:
Don't get/be _, you can't drink all that in one go"
If there are various related words or expressions to be used in different situations, I would like to have all of them with appropriate examples. Thanks.
