It seems lower is better with bupe. The agonist happens before the antagonism effect, which one person thought led to discomfort. The idea is to use just enough to get the agonist effect without using enough to the antagonism effect.
Edit: Fight your pm doc on kicking you out or finding another. Cannabis is too accepted for pm docs to kick out. It's not for your safety, but so they don't get shit from the feeds. It's BS. You shouldn't be forced to subs if you utilize cannabis, which is a great pain relieve and works best with opiates. Using opiates alone always leads to tolerance building quick and high dosing, but I find using cannabis helps me keep my opiate dose low and vice versa. Bupe can be good for pain, but imo nothing beats the classics especially oxymorphone for nighttime with its super selective nature and long half life as well as oxycodone for pain relief when one needs to function. Both being very similarly shaped to natural opiates leads to similar effect just longer for some specifically oxymorphone (7-8 hours vs 2-3 at best like other classics) unlike bupe, methadone, tramadol, Levorphanol, etc. That not just have strange opiate activity, but activity spread in other areas to make it slightly NMDA active supposedly to reduce dependency or tolerance buildup (don't remember which) or tramadol that's more of an anti depressant with opiate activity vs. an actual opiate with extra activity. Don't let them control your brain by limiting it's chemical access our forcing to stimulate possibly unnecessary areas with compounds that are accepted and profitable vs things that may help, but don't help the doctors and drug makers fill their pockets. It is your patient right to be provided proper pain management meds and not be forced into matinance on non preferred meds that could be detrimental even if a life saver for your doctors convince.... It's not about the doctor feeling comfortable, but for you to feel comfortable. It's just up to you to demand your patients rights and fight for them. Trust me it is hard especially when treated like a no good drug person. Honestly at this point I can honestly say I haven't seen a single non drug user for a long time at least one who has already done drugs before. Anyways good luck and hope my words helps
