I am using chantex and I also am in the methadone clinic, but i have noticed that I am still feeling sick after dosing and it only started after I started using the chantex. I am asking because I read that nictone attaches itself to the receptors in the brain and herion also attaches itself to the same receptors, so if it blocks nictone from entering the receptors wouldn't it block herion(methadone) I really want to stop using methadone but am afraid of the wds. I know hoe I felt wdn off of herion and heard methadone was worse. I don't have time to lay in bed sick> I am a mother of 4 and a full time college student. Could anyone help? any info is greatly apprectiated.
