I am prescribed morphine SR (150mg's a day) and clonazepam (6mg's a day) along with the non abusable meds i am on which are:
Gabapentin Tapered down to 800mg's a day but i am prescribed 3200mg's a day)
Buscopan (Butylscopolamine) (about 30mg's a day)
Lamotrigine (200mg's a day)
Quetiapine (300-400mg's a day)
Bupropion SR (300mg's a day although i sometimes stop taking it when depression is not a problem for me)
I have trigeminal neuralgia as well as bipolar disorder. It's very easy for me to abuse my meds and come up short as it not only helps my physical pain but also mental pain when i am having a depressive or manic episode. I don't run short on my clonazepam as i don't find that it's worth abusing and if i ran out on the dose i am on which is 6mg's a day after being on it about 8 years i would be in big trouble. But i do often come up short on my morphine especially if i am feeling depressed which leeds to withdrawals and worse depression

. This often leeds to me getting some dilaudid or another opiate i am not prescribed which i usually IV. So it's a vicious cycle for sure.
I have tried most non opiate painkillers out there for neuropathic pain including carbamazepine, the tricyclic amitriptyline, pregabalin, gabapentin which i'm on now but doesn't really work hence why i am tapering, Divalproex (trade names Epival, Depakote, etc) which i tried for bipolar disorder but it's also used for trigeminal neuralgia like many anti-convulsants, clonazepam, lamotrigine, Cannabis and ketamine. Out of those only ketamine matched morphine in terms of killing pain. Although i do smoke a fair bit of Cannabis and Indica strains of weed and hash certainly help alot. Unfortunately ketamine is only used for anesthesia here in Canada and the medical Marijuana is supposed to be shit and it's nearly impossible to get anyway. I could get Marinol if my doctor bothered to prescribe it to me as it's the only Cannabinoid covered under my insurance. The much better Sativex spray i could get on prescription but i could never afford it. So unless they approve ketamine to treat neuropathic pain in Canada j am stuck with opiates.
It would be worth trying a non opiate painkiller like a tricyclic anti-depressant. I don't know what other meds your on but tricyclics are safe to mix with Lithium. I found amitriptyline to work pretty good and it helped keep my opiate tolerance down. However due to it's cardiotoxicity it might not be a good idea to mix it with Dexedrine. Gabapentin or Lyrica would be fine to mix with the meds you listed and would be worth trying if your pain is neuropathic in origin. I found Dexedrine itself to drastically reduce my tolerance to opiates actually as it does increase the analgesic and euphoric effects of opiates across the board. I think your best option would be to do a taper on the opiates and get your tolerance down abit. I don't know if you smoke it but Cannabis can make that alot less painful and it does help you spare along the opiates. I have been on opiates on and off (mostly on) for about 8 years now i guess and for most of that time it has been morphine SR. A few tolerance breaks i took did help as much as they sucked at the time
