Hi guys, I'm having a little trouble staying in state at work - hopefully, someone will have good recommendations. Backstory: I went to an awesome party on Saturday and was in great spirits for the remainder of the weekend. Even on Monday, I still had a good buzz going. However, the general ambiance of my workplace (science lab) is so crushingly depressing (nobody here smiles because their dreams have all been destroyed) that by Wednesday, I am completely defeated.

How do you guys stay in state throughout the week? FYI I am working on leaving this job but need to stay a year to finish up my project, out of respect to my boss who has been nothing but gracious to me.
