It depends xuser. Depends on how motivated you are, how long you've been on the suboxone, how long you've been at your current dose.
My withdrawal was enough to make me not want to go to work, but I still did. Just make sure you have some loperamide. You may be able to get a sick note from your Doctor for the very worst of it - I'm sure they'd be understanding especially for a new job. I think it does help to be doing stuff during the wd though. Tires you out and keeps your mind busy.
Depends what kind of work it is. Coming off 2mg wouldn't be good if you're a paramedic or something
Generally the lower you get the easier it is. Lots of it is mental. You could probably get a script for the 0.4mg subutex tablets, I think it's 8 weeks they give you on those for the last bit of tapering.
I'm currently on 0.8mg, going down to 0.4 tomorrow. It won't be much fun for a few weeks, you need to have your goal fresh in your mind and know why you're coming off - when you're feeling crappy remind yourself that it won't last forever.
If you suddenly stop taking 2mg - I wouldn't even expect the proper withdrawal to start for a few days. So yeah it's going to be longer than 3 days. Again - depends how long you've been taking it.
I'd personally try and taper a bit lower. If you have a bunch of films you can snip them into tiny pieces and very slowly bring yourself off.
