Starting from the upcoming semester besides my research for the PhD, I will also have to work on a loosely related project (w.r.t. my research), and do teaching as well.

I am overwhelmed from this. It seems that I will never have enough time for the actual research while the project work (50%) and teaching will eat up all my time.

Besides these duties there are also students to supervise, lab to maintain etc.

How do the more experienced ones in AcademiaSE deal / have dealt with such situations?
