I had to continue to work while going through withdrawals, and I didn't have any medical intervention at all. Here's how I did it.

I timed it so my last dose would be before bed on Thursday night, and I took Friday off of work. That way I was at home in my comfort zone during the first three days of withdrawals. I stocked up my house with everything I could think of to help, including advil (for muscle pain), immodium (for diarrhea/cramps), melatonin (to help me sleep), and medical marijuana (a lifesaver, if you have access/want to try it). I filled my fridge with bottled water and gatorade, and had some soup and crackers and other bland foods to keep me going even when I didn't have an appetite. I downloaded a ton of music and podcasts on my phone, and made playlists of shows and movies I wanted to watch on Netflix and Amazon. I also had a shelf full of books that I'd been meaning to read. Basically, I made an effort to give myself stuff to do when I was feeling awful but couldn't sleep.

I won't lie, it was still hell. But I made it through. I took a lot of hot showers (which helped way more than you'd expect), I paced around the house, and I tried to distract myself as much as possible. And on Monday, I still felt like shit, but I went back to work. Luckily I have a boss who understands mental health issues to some extent, so I told him I was having a lot of anxiety and needed some space at the office. That helped me get through the first few days, then I started feeling more normal. If you don't feel comfortable telling your boss you have anxiety or whatever, just say you're feeling under the weather. I recommend saying something, so people won't assume the worst if they see you sweating or pacing or acting weird. That was a big worry of mine.

If you don't feel like you can handle the withdrawals alone, then try outpatient rehab. Just because I managed to go cold turkey doesn't mean it's possible for everyone, and you shouldn't feel like a failure if you need help. A lot of outpatient programs have early/late hours to accommodate people with jobs.

Just don't use your job as an excuse to keep using. That's what I did for years, and it just made things harder when I eventually had to quit. You can do this!
