What would you do to prepare for an Ayu concert?

I went for artist concert twice and two of them has the venue in the big cities. I have to travel around 4~6 hours to reach the stadium. Based on the experience I have, I'd say keep your body energy is the most important. I remembered well I took an overnight bus to reach the venue and I cant sleep well, I only slept for 4~5 hours, and I even take a long walk to walk around the city before the concert begin xD, and what happened to me, I keep yawning and feel sleepy when the artist start to sing ballads song xDDD And I was quite surprised to myself because I have this feeling "ooh I wish I could just 'next' the song" aww that was awful, but yeah I used too much of my energy before the concert and thats the result.
