At the beginning of term I went home every 2 weeks, as did my flat mates.
However, it was less and less and usually went home every 3-4 weeks.
My uni was only an hour and a half drive away so my dad drove me back on the sunday evening.
However, the uni i'm going to this year (changed unis) is 3 1/2 hours away, so i'm thinking the visits will be less frequent which is sad.
It's weird going home after a while it's all weird being back in your room and bed. Well, for me anyway!
