My girlfriend keeps calling me over and over right after we hang up..

‌We both love drinking. My girlfriend loves it too.
We both have jobs that allow for a flexible schedule (though she is essentially unemployed). In the early stages of our relationship, we spent an entire week doing nothing but drinking from the moment we woke up.ㅡㅡ
We spent too much money... couldn't get any work done; so we decided to snap out of it and get back to working hard.
But since she's bored at home, she's always plotting ways to drink with me and trying to seduce me (even though I need to work;)
And while I'm trying to focus on my work... if I'm not exaggerating, she calls me more than 10 times a day;;
The funny thing is, even after I ask "How did you know?" and hang up, she calls again within 1 or 2 minutes.
And then she calls again.;
Yesterday, I came home around 8 PM after working and I was exhausted,
but she called to tempt me to go drinking;; I barely managed to make an excuse to say no, but she kept asking if I really wasn't going to drink.
She called in the early morning, when the sun came up, and even just now at 6 AM.
I told her I couldn't sleep and hung up, but she called again.. I answered and hung up.. she called again.
I finally exploded and told her I was annoyed.
I snapped at her, saying she should go find a restaurant to work at, and that she's only acting like this because she's bored at home.ㅡㅡ
