most of you sound like you have thyroid problems or are on too high a dose.
I have been on Methadone for 40 years. Now 90mg. a day it's expensive...300 a month for once a month regardless of dose. I go once a month because I never use other drugs.
The biggest problem is getting off.
after 6 to 10 years, you can't unless you replace it with other drugs. I run a fortune 500 company, so it shouldn't effect your lifestyle.
My first year on methadone, I totaled 4 new cars.....you learn not to drive a hr. after your take your dose if it's high. Don't learn the hard way.
