You can! You may need to take a norco or vicodin the day before your appt so opioids shows up in your urine. Do not take any benzos! (It will open a whole other can of worms) Yes it will be fine while you've been taking sub & no you wont have withdrawals. Your Doctor may or may not "induce" you on your first appt meaning you go fill one sub at the pharm, then return & take it while they monitor you to verify that you can handle this drug, & they can also confirm no allergic reactions or precipitated withdrawals.
Personally I would NOT mention that you've been buying sub off the street. My experience with that is that the Doctor's get paranoid with patients that are buying or selling meds illegally only because the DEA sweats them about drug diversion. Be prepared to provide a clean urine specimen every month (positive for sub) another thing, your Doc will likely make you see a counselor or attend AA/NA & provide a signed sheet as proof. Best of Luck
I’d advise you to just go to the dr. & not take anything else..... if you’re on suboxone & take anything with opiates in it ( Vicodin-oxy-norco) it will send you into precicipitated withdrawals & it’s a nightmare. Not trying to scare you, learned the hard way. And taking more of the subs did not help. Just tell doc you’ve been getting them & would advise going on a slow taper. Been on them for 7 years & years devastated my health. Blessings & best wishes
