Someone or something you definitely could live without.
Okay, okay, but seriously…I’m not sure if this is supposed to be something that you wish you didn’t have to deal with, or something that you wouldn’t miss if it was gone. I’m going to go with the latter and say alcohol.
Don’t get me wrong, I enjoy my booze. I love going to parties with friends and getting my drink on. But if I had to give something up permanently, it wouldn’t hurt me too badly to give up alcohol. Being pregnant (and breastfeeding afterward) made me realize how unimportant alcohol is to me. There’s nothing quite like a nice cold drink, but it’s not something I’m going to pine after if I lose it.
