Having worked in a large hospital lab for 25+ years, I can understand!! My schedule was never quite as crazy as yours however...!
One thing to keep in mind is that you are likely getting more exercise than you realize! Most Med Techs are on their feet and moving around way more than most jobs. Have you ever worn a pedometer to check if you are up and about much? I don't know which specialty area you work in or how automated your environment is--that will certainly make some difference as to how much "running around" you do. If you have "remote" lab sites (we did down in the OR/Blood bank), ask to work there--that hallway mileage really adds up!
On another note (re: the schedule) have you considered having a good chat with HR or a Union Rep?? If so, besides asking about the policies regarding how much notice they need to give you on shift schedule changes, you might express your concern about health effects from this craziness (Sick Time = $$$ in Admin speak!) and Retention (Training=$$$ in Admin Speak!) Large institutions might also be able to provide a "counselor/coach/mediator" to help your work group come up with a better plan for managing the schedule if THEY can convince the Supervisor (she) could use the help. I know that's a REALLY touchy area however! (Been there-done that!) We used an "On Call" system where each week/weekend a different pair of folks were on the hit list. Then at least you could have a chance at some definite down time....
Enough of my ramblings! Wish you the best on all this..... Remember to eat healthy, and take care of yourself the best you can!!
Remember...One Choice At a Time!
