That is funny sister. The same thing is going on in my office today.
If you are practicing the deen as you say you are I am confident that if a glass of wine was placed in front of you, you would not want to drink it.
I just went through the same ordeal. In the back of my mind I was remembering how much I loved wine with my evening meal. Yet at the same time I rememered how proud I am that I was able to quit that haram. Even more so, I am proud that, despite all of the pressure around me, I am able to ignore everyone and continue living the way Allah told us to do.
Just remember, shaytan is with us at all times and he is testing us.
If you are too shy to say anything to your coworkers, try changing the subject. I'm sure they wont even notice
