stop it. Suboxone is way easier to quit seeing you can taper down quite easily. There are dozens of guides on the internet about long tapers and how the trick is to get to 0.5 or 0.25mg a day when you jump. At which point any sickness is quite benign.
That hasn't been my experience at all. I've been tapering for the past year (after 3 years on 24mg) and have only managed to halve my dose, and even then have gone through discomfort plenty of times when I made the mistake of reducing too fast. Granted I'm fairly sensitive to the withdrawal, I imagine thanks to the number of times I've put myself through it due to what my pattern of use was like (I suspect a process like
https://en.wikipedia.org/wiki/Kindling is in effect, and friends have had similar experiences, although it's only been studied for GABAergic drugs), but I've spoken to other people tapering and it isn't the painless, breezy process you describe.
I can't speak for actually jumping off, since I haven't gotten there yet, but here's an article by a suboxone doctor about what to expect after jumping off long term use
http://www.pbod.org/detoxing-suboxone-fear-caused-lack-knowledge/ . And I did fairly constant "mini-tapers" during my first year on the program so I could swap back to other opiates for a few days, all of which were very uncomfortable. You can spread out the process as much as you want, but getting your brain back to homeostasis after bombarding it with opiates for an extended period of time is going to involve discomfort as some stage or another - just a fact of life.
And Mostly-Human is right, even a low dose of suboxone is going to have a strong effect on someone used to CWE's and equivalent seed tea doses - and clinic doctors don't generally prescribe low doses, instead generally pushing patients up onto the higher doses (16mg+) to make them more firmly dependent on the suboxone and thus less easily able to revert to other opiates. So it's quite likely that OP will walk around fairly fucked up every day (and not in a fun way) for a few weeks/months, and then be left with a big habit and the consequent side effects.
Then there's the whole issue of actually, you know, being on the program. It's cheaper than other habits, but the daily $5 - $10 still adds up. And there's going to pick up your dose every day (for a year, until it's just every other day, and then in another 6 months you "only" have to go in twice a week), and if you're at a clinic (thank God I dodged that bullet) I've heard nothing but horror stories about the nurses, the doctors and the other clients (oh, and the urine tests). And just as a bonus, you instantly get thrown into the "scamming drug addict" column by every doctor you see, which is fun.
I'm not saying people shouldn't go onto suboxone (although the system does need some major reforms) - someone has to make that decision for themselves. But getting onto suboxone after CWE/PST abso-fucking-lutely is a big leap in terms of upgrading your opioid dependence, and it comes with a whole load of financial, social and medical baggage. And getting
off suboxone is nowhere near as easy and painless as just cutting a slightly larger slice off your dose every week. And then you're right back where you started unless you've actually used the time on suboxone to figure out why you became so enamored with opiates and how to get your life and your head in a place that will allow you to live life without them.
All of that should be taken into account before the decision is made. In this particular case, I would say at the least that someone in the OP's situation should at the least make a couple serious attempts at a self taper (with guidance from a doctor and a mental health professional, ideally) before considering suboxone.
