Congrats! My first day was almost seven months ago (my, how time flies) ad although some days may have been difficult or lacklustre for various reasons I still treasure everyday that I can go to work as Grace and not as dude me. People were and continue to be supportive. If people used my old name or misgendered me (which you'll probably find will happen, even if by accident) I just asked "who?" until they corrected themselves. Seemed to work well as a teaching tool. Hope you have many great days, months and years. (If my work wasn't so sucky at the moment I'm sure I'd be enjoying it even more.)
