How long will this hangover last?!?

Ugh, last night I went out drinking with some friends and got completely HIT. I had 7 drinks (2 margaritas, 2 pina coladas, 2 strawberry daquiris, and 1 beer) and now I`m HUNGOVER the next morning. I feel awful! This was my first time drinking and I don`t think I`ll ever do it again. (lol) I`m also a petite girl weighing around 105 at 5`4 (no I don`t have an eating disorder, I`m just naturally thin) and I heard it`s harder on our bodies. Is this true? How long will this miserable feeling last?
