definitely normal for missing a dose. its giving you a taste of withdrawals I'm sure. withdrawals can make you feel extremely weak, and I know methadone being one of the strongest opiates its probably very bad. I used to wake up every morning sick when I wouldn't take norco right away, my body was already feeling w/d from waiting 8-9 hours between doses. best wishes on your taper!
What you are experiencing from missing your dose is very normal...I was on methadone for almost 2 years.I went c/t off of 25 mgs and I'm coming up on 10 months clean.If I can help you out in any way please fell free to shoot me a pm anytime.All the best...Kim
Sorry it took so long for a response and im no help with this question, just wanted to bump it back to top for someone that knows about methadone. good luck.
