I Don't Usually Drink But I Got Drunk Saturday Night,

I don't usually drink but I got drunk Saturday night, I ate some McDonalds and it made me start to not feel so good and I threw up, payed down for a long time and then I went home with my boyfriend and fell asleep. (I don't eat fast food either) I woke up hungover and I still feel like complete crap days later (Tuesday) My head is dizy and feels strained, I feel like I wanna throw up all the time and I'm so tired.
