Diet coke addicting. will this affect me in my basketball game wich is in 1.5 hours?

I have a bball game in an hour and over lal today i had 2 and a half d8 oz cans of diet coke. I was thirsty this morning and i had no juice or milk in the fridge so i figured y not take a diet coke ( i rarely have diet cokel, or soda in general (besides asian soda)) It wasnt that good but it made me thirsty and icraved it sooooomuch and i just took it again and then a 3rd time but threw it out half way through cuz im like this cant be healthy. why is diet coke so addicting , is it worse then regular soda and will this affect me?
