How should i say this...

my best friend can not handle her alcohol. it’s gotten to the point where i genuinely do not enjoy having drinks with her. she never knows her limits and ends up puking (A LOT) every single time we drink, it’s not only that it’s that she tends to act very rude when she’s like this, for example i had made her some food one day her favourite of my recipes took an hour i felt bad she was super drunk and she needed some food, she took two bites said “it’s different” and that was it she put it away. i don’t think she does it on purpose but it’s annoying that i have to deal with it everytime. . when she says she wants to have some drinks i get nervous i don’t know what to say anymore obviously i enjoy having some drinks here and there but whenever it’s with her i don’t want to. i’m not mad that she gets sick and starts puking it happens it’s just that it happens every single time and she’s fully aware that it happens and it kind of ruins my night because i have to deal with it. it’s even harder because we live together.
