i've read the older posts on different substances that potentiate methadone. cat's claw, grapefruit juice, magnesium. i'm taking 100 mg. methadone daily. i tried dxm and didn't care for the way it made me feel. i have two questions:
1. are there any other substances that potentiate and won't test positive on a drug screen?
2. what are the suggested doses for the three listed above?
thanks everyone and great forum you have here. i just discovered it last week.
