Lab Day 1: Freaking tired

First day at lab is so taxing.

Woke up at 6am, attended class till 12.30pm.
Started lab at 1pm, finished at 6pm. Went to gym for one and half hour. Went home, stuck in jam and finally reach home at 9pm.

My daily routine is gonna be like this everyday for 3 months, except on Thursday and weekends, which are allocated for my thesis writing.

Just day 1 and i'm already hating it. How can i survive 3 months?
