Bingo. I like my fulltime job. I make decent money, I have gained a HUGE amount of experience seeing only ALS calls, but it has taxed me mentally and physically.
I am assigned to nights, and sleeping is forbidden. Trying to sleep during the day is next to impossible. There are no kitchens, or appliences to use to cook a healthy meal, so it is whatever is open (usually fast food, or something you can pack, and quickly reheat, and usually not so healthy).
I have raised my systolic by 20mmHg, my resting HR by 10-15BPM, and increased my BMI. My cardio shape has fallen to pieces, and I am suffering from seasonal affective disorder from the lack of sunlight.
At my parttime gig as a FF/EMT, we all sit down together to eat meals, try to eat healthy, and sleeping is generally from 2100-0700, with naps allowed for those who get their butts handed to them at a previous job, or the tour before.
Although working out on duty is not allowed, that could change.
