The idiom for this week is for something to “go to someone’s head”. It is used when we want to talk about a person who becomes conceited because of some success they have had or some accomplishment they have done. For example:
Winning the bowling tournament last week has really gone to Jim’s head. Now he thinks he’s the best bowler in the world!
Don’t give Patty a compliment about the way she looks. It will just go to her head.
Richard got a promotion last year, and it really went to his head. Now he thinks he’s so much better than everyone else.
I’m happy that you were successful with this project, but I hope you won’t let it go to your head.
So, as you can see, we use the accomplishment or success as the subject in the sentence. By the way, if you don’t know what the word “conceited” means, you can check my blog for last Wednesday. I write about it in more detail there.
We can also use this expression to talk about a situation in which a person is easily and quickly affected by drinking alcohol. For example:
I haven’t eaten anything all day, so this beer is going straight to my head.
My boyfriend is a weak drinker. If you give him anything with alcohol in it, it goes straight to his head.
Beer doesn’t affect me so quickly, but wine goes straight to my head.
As you can see from my examples, we usually use the word “straight” in these sentences.
