back at work second day surprisingly not too tired, now yesterday was another story

my first day at work was not too bad, i was very tired by the end of the day, becuase i didn't get much sleep the night before, trying to get back on track with my schedule, it's really hard when you've been up late at night for weeks. Since i have to take public transportation I have to leave my home early so I can get a sit on the train and want to beat the rush. Other than that very happy i'm feeling good and finally getting back to my old self again.
