"this medication has worked far better than any of the other medications that i have tried before, including fentanyl, percocet, and morphine. i still have a lot of pain, so i do take another pain medicine between doses because it is necessary. methadone controls my pain for longer periods than any of the other medications that i have been on. in my personal opinion, as long as this medicine is used as it is prescribed, it is very useful and the benefits are astounding."
