What can i do about an ear infection?

Last week i went to the dr and he confirmed i have an ear infection. I just finished the antibiotics he prescribed for me this morning.

I’m already experiencing the same symptoms again :(.

I was wondering; does it just take a little while to feel better? And if not, what else can i do? I don’t have the time and money for another dr visit, and i don’t want to be overexposed to antibiotics anyway
