Hi I am sorry to read your situation. I am a addict who has been through meth and am now on espranor (subutex). There are some great services available to people in this situation and the best advice would be to switch to subutex…it acts as an inhibitor and the longer you are on it the more it takes the cravings and eventually even the thoughts about using. Speak to the meth clinic and they can arrange it.
Subutex is a replacement used for quick treatment with the plan to reduce until it is stopped in a short time span. Unlike methadone which most people abuse at the same time as heroin.
I am 18 months clean and I hope your partner can beat this…it ruined my life and I am never going to be the person I was before.
All the best.
