Back to the drawing board.

I started my new job and its been a month since then but yet there is something missing with this job. Usually when i start in a new place i easily settle down. I guess my heart is rejecting everything about this new place but my head keep on saying keep going, keep going. Both are not syncing. There must be something wrong with this place. The best answered is "your not happy". Anybody have ever experience this kind of feeling before? i guess back to the drawing board again. Another job interview here i come..
