Welcome to the DMT-Nexus.
Iboga can indeed help with the reduction or elimination of addiction to a substance, including morphine.
You have to remember though that getting rid of your bodies addiction to a substance is part of the total picture. Without taking care of the other parts you might be back to your addiction before you know it.
The other bigger part is your social life and the people you hang around with. If you do not change those as well then your success rate to kick the addiction for good is rather low, being around the wrong friends for example makes it really hard to withstand the temptation. Also your new life should have people around you that support you with getting rid of your addiction since it might be really hard at times to not fall back.
So make sure that you work on those parts really hard too, it's not only the Iboga!
As for taking the Iboga, make sure you have a sitter with you who is experienced with this, a good Iboga flood dose will last for several days, also the after effects might last a lot longer. It might even be worth to go to a special Iboga rehab for this.
Rests me to say that after an Iboga addiction reset, your tolerance to drugs is gone too. So overdosing on morphine after the Iboga therapy is very real, taking the same dose as that you are taking now will likely kill you! Please keep that fact with you all the time!
I hope that you find a way to get rid of your addiction and that you will find your old you again.
Kind regards,
The Traveler
