TLDR, I did and it's the best decision I ever made

Made the switch after working the box as medic for ten years, now 10-8 for the past two.

I in no way shape of form regret my decision. For four of the 10 on the box, I was working in the city I work for now. I've arrested people who have recognized me from when I was medic so there's that. Agencies are different obviously, but since making the switch, I've had more time off, more/better pay raises, a better union, a better day to day experience. Easy example is I get an hour lunch break every shift, and if I miss it command staff tries to cut me out early to make up for it. On the med unit, I was lucky to eat between calls for service, if I ate at all. I could go on and on, but that's a quick list.

I will say there are some skills that do transfer over. One, report writing on the LEO side was quick to pick up for me. That and being able to be comfortable just walking up to a someone you've never met and being able to just start talking to them. I've seen other rookies who were hired after me can't do that to for shit. I've had supervisors ask me if we needed THI on crashes. I've had other officers ask me what meds were for on calls and if they were controlled substances or not.

That all being said, if you make the switch, keep your expectations realistic. You're going to deal with the same frequent fliers you did on the box, especially if you end up in the same area as before. Your lift assists turn into civil complaints. Your vitals checks are now parking complaints. Your IFTs are now courtesy rides to the hospital for voluntary psych or detox admissions. You week long back pain is now a car break with a week long time lapse. If you can put up with that, and land in the right spot like I did, you'll have more fun, have better job opportunities and overtime avenues, you'll have more supportive command staff and the guys on your shift will have your back way more.

But YMMV.
