And this my friend is how addiction starts. You chase that feeling never fully capturing it and the more u do the farther gone u become from the reality of "I'm now an addict
If you are taking Methadone for the high/good feelings it gave you, then you are taking it for the wrong reasons completely.
Typically, when you are put on a long term pain medication, your body acclimates to it, and you stop experiencing the side effects that someone new to the medication would have for a short time. It is called tolerance. I was on methadone for severe back pain and I never, ever got "high" or felt good, happy or whatever you want to call it from it. If you are getting high or increasing your dosage in hopes of recapturing the "high" from it, you are not only in danger of loosing your pain medication from your doctor, but you are in serious danger of accidentally killing yourself.
Methadone has a long half life, which means that it stays at a certain level in your bloodstream over a longer period of time . Doubling your dose as you are doing means that you are increasing the cumulative amounts of methadone in your bloodstream and because of that, you can cause your body to develop respiratory suppression , and you can die.
You need to stop increasing your dose on your own without your prescribing doctor's permission/knowledge. You are playing a dangerous game, one which can cause you to loose your life.
