Since you only took 1 small dose of methadone, if you wait about 24 hours hydrocodone should still work. Maybe 48 hours at most until you can feel the full effects again.
At 10mg, the blockade effect of methadone is virtually non-existant.
This is a very basic question, so I am going to close it. Please review the BLUA and Other Drugs guidelines & posting standards, conveniently located in my signature. Feel free to private message myself or any other staff member with any further questions.
