What things do you waste your money on?

i really dont know..i came to the netherlands with plenty of money in my bank account, but 4 months later..it's all gone. i have no idea where it all went, and i dont feel like i spent that much money on things i didnt need! i went out to eat a few times during the first month or two i was here, but i haven't done that since. and i was going out a lot and drinking, but i also havent done that in more than a month. i spend like 80-90 euros a month on my groceries, and ive bought a pair of boots and about 7 long-sleeved shirts for the winter, but they were all really cheap. i travelled to my aunt's house 3 times, to my boyfriend's once, to belgium once, and to amsterdam once, but i haven't done any travelling otherwise.
