I just use whatever device I brought to work that day. When I feel the need for some nicotine and can't get off the floor, I just hide in the bathroom for a little bit or shut the door to another room and stay out of camera view. I generally tell my co-workers where I'm going in case they need me. It's not as good as being able to walk to the .... hut and sit and relax for a few minutes, but it does the trick. Obviously, since we have a .... hut, smoking is not prohibited where I work. I have no need to hide any of my vape stuff; it's usually sitting in plain site on the nurse's station. I've had lots of conversations about it with staff and patients.
