I was wondering if it was ok to take doses of codeine aswell as a daily dose of methadone? A daily dose of methadone 20ml taken at tea time each day so would it be ok to take regular doses of 30mg codeine throughout the day aswell ( i have a very high tolerance codeine to the point i can take betwenn 400mg and 800mg a day and not feel very high and get little pain relief to ) . I have read that it can lower heart rate and respiratory system but if the methadone has adjusted in your body and you are used to it now and also have tolerance to codeine does it mean that you can take the 2 together without risk of OD?
