Travelling for work

I currently have reduced working hours due to "allattamento" or lactation, which allows me to leave work 2 hours early, until my baby is one year old. My problem is that once this period is over, and I resume normal work hours, I will also be expected to travel again. I put the thought off since it seemed so distant, but now that it is getting closer and closer, I am starting to panic. I don't know how I can possibly leave my baby for a whole week. Is that not traumatic for the baby? I think things like that should be eased into, should be done gradually. Unfortunately employers don't give a shit, and just want to get the work done no matter what. We'll see what happens, for now, I am in total panic mode.
In other news, my diet is moving forward, I have started counting calories since Friday, and am doing well so far. Desperation has led me here. I tried watching what I ate, and made moderate changes to no avail. I hope this second phase works since I have no clue what to do after that!!!
Any post baby diet stories out there??
