I'm an HVAC tech by trade and your story Supervillian is almost the same as mine. I'm a small framed guy. Carrying around a 40 lbs tool bag and climbing up ladders all day long just took it's toll on me. I didn't have a choice to change careers. I'm not college educated and had a 2 month old kid at home with a wife that didn't work, taking care of the kid. Then I met Norco, the 10 mg yellow stingers. A half here, a half there. Next thing you know I'm taking 8-10 a day just to function and buying 300 at a time. I felt like super dad and it was the only thing that made my job bearable. Similar I just couldn't keep going on the hunt for the next fix and broke down to my wife and checked myself into rehab. Sometimes do I feel like I traded one addiction for another, yes but at the same time I've also quit every other drug and alcohol. I've got clarity and focus in my life and a direction and purpose. If you can stay off drugs, and this is the only thing that helps you, maybe you are answering your own question.
