Hi my neighbor's giraffe's pet fish is new to methadone and today is his first time taking it. He blew two percocets earlier this morning at around 1-2 and now he just took 2.5 mg of methadone, because he has been researching it and he doesn't want to do too much his first time. He has a decent opiate tolerance, he recently cut down this week going from 30mg as an okay high to 10mg a day this week to ween off. is it okay to take be mixing that? i need to give him some advice!
