Not full time before. I was previously doing research the rest of the time. Actually, I think this semester was a bit more than full time teaching. You disappeared for a while...I moved departments and am doing considerably less research. Got tired of banging my head against the wall and praying for funding and opted for just teaching with a little collaborative research on the side. Compared to research, this semester has been a breeze, actually. Just this week has been hectic, because I was literally expected to be in four places at once today with exams for the courses I'm teaching ALL conflicting. And, of course with final exams looming, I couldn't so much as walk the three doors from my office to the bathroom without a student jumping out from a corner and asking me questions.
Next semester will feel quite easy by comparison...it's back to teaching the med students in the course I've been teaching all along, with plenty of time to work on other endeavors. I'm starting to write a textbook, for example. I have a pretty good outline worked out, and all of chapter 1.

It'll be nice to have some time to get back to it in earnest. I want to offer as much of it as possible to my students next year as a supplement to their required text and see how they perceive it so I can edit accordingly.
