What is the high like on 10mg methadone?

Well it depends... If you have never taken Methadone before then it is possible you will feel a slight to moderate "high" or "buzz" or you may not even feel any high at all. 10mg of methadone is a very small amount so in my personal opinion I wouldnt really expect to get really high. When I first took methadone I was given 30mg at a clinic and I was VERY high, but it did take almost 1-2 hours to take effect and the high lasted almost 2 days. I had an oxy-80 a day habit and didnt take anything for one whole day, then got my 30mg dose of methadone.
