These guys give excellent advice. Iboga can take away your cravings, and can reduce the withdrawal to almost nothing. That is only the first step, though. The key is finding another purpose in life, than just getting high. We become entrenched in acquiring our next high so much, that we lose our identities as anything else. Finding a new hobby, a new job, getting away from our old scoring spots, and using friends, all are necessary steps in really quitting.
It's very hard to take away the drugs, but continue our lives exactly the same in every aspect. It's just not going to work for most people, if they don't change their whole lives, especially when they have spent so many years in this habit of up and down that is opiate/opioid addiction. I hope we can help you figure out your plan of action and offer enough good advice that you can finally see the light at the end of the tunnel.
Know that iboga is a miracle in how it can take away so much pain and craving in a single dose, but it still takes major work on our part to make that stick. We need to learn all new healthy habits, rather than falling back into our own afflictions out of ease, and familiarity. Change is good, and we all have that power. Iboga will show you this, but what you do with that new found knowledge is still up to you!
Best of luck, and welcome to Eboka!
