The consensus is methadone for pain doesnt get you high like other opiates. why do i feel a sedate happy euphoria if i miss a few doses then catch up?

Not consensus at all: If used PROPERLY, and titrated correctly to the right dose, it should not. However, when you miss even 2 doses, your tolerance starts to go down, and most programs will reduce your dose if you miss 2 days in a row. In addition, adding other drugs to it (benzodiazepines, other sedating agents, alcohol) can contribute to feeling euphoria. Missing doses is continuing an "addictive lifestyle" .
