Short answer is that you have to answer those questions for yourself. The long answer is...
Basically it's like this: the vast majority of people in recovery are not medical professionals and have no business telling you what meds you should or shouldn't be taking. On top of that, most doctors who work with current or former drug users have little to no experience with it. So you're kinda left in a place where you have to do your own research and make up your own mind about what you need to help you achieve your goals.
My goals have always prioritized QOL over total abstience (I don't really give a shit about using drugs if I'm even more miserable with it). In fact, unless your drug use was directly harming others (such as when alcohol users get violent/abusive), it isn't even the drug use that is the problem. Furthermore, not all drug use is created equal - drinking booze for someone who has a tendency to get abusive and violent under the influence is far different from replacing it with an appropriate medication like baclofen.
Does the drug use or medication lead to creating more or less harm in your life? That is perhaps the question for you. And what's more, is it keeping you from achieving your goals. And I'm not talking about the long term goal of total abstience, I'm talking about growing and developing as an individual, getting things straight with housing, employment or school, getting ones mental and physical health in order, etc.
What are YOUR goals in this dreamflyer? If we could put the question of abstience aside for a moment, what else do you want and need out of YOUR recovery?
If there is anything I've learned, even among 12 step bleeding decons, each of our recovery processes will a little different. There is no one path to recovery, only the path you create for yourself. And what that looks like depends on your particular needs, wants and goals.
As I like to say, sobriety is first and foremost a state of mind. Drug use may or may not keep you from achieving such. What has been kind cool for me to experience is that, as I have begun to achieve my own goals in this more and more (no longer engaging in illegal behavior, more or less healthy relationship with family and friends, no longer using opioids, learned how to meditate, got into a good grad school, etc), I am simply less and less interested in drug use. I have experienced something similar happening for almost without exception others I've met in recovery, regardless of whether they went an abstience only route or slowly reduced their use and switched to less harmful substance use.
Something else interesting to point out that might be helpful is that the abstience only model is actually itself a product of our drug policy (prohibition and the war on drugs). That is a model rather ironically rooted in a lopsided focus on public safety. If you want to take a more public health approach to your recovery, abstience (whether its total abstience from all mind altering substances or abstience from harmful behavior) will end up being the result, total abstience not so much the means.
Perhaps it might be helpful to distinguish between abstience and the more black and white total abstience from all mind altering substances. I focused on abstience, first from heroin, then methadone, then other drugs more and more. Abstience from harmful drug use doesn't necessarily require total black and white abstience. I'd focus on dealing with the more problematic issues of your habits, not limited to drug use, and go from there.
This stuff is so personal, it's really a developmental/learning process. And that takes time. Learning takes making mistakes. Recovery requires two things really, keeping yourself alive and learning to become more resilient. As hard as it is, it's actually kinda a blessing. Few people get such a chance to reimagine themselves.
If you don't already have your own recovery journal thread, I highly recommend you start one. You'll get good support. And I'd love to hear your story.
Recovery is never a black and white thing. It is a process. My short and long term goals have always included abstience, but they include far more than just that. When abstience is your only identifiable goal, that is when I tend to see things get problematic.
