How Long After Quitting How Long Does Methadone Stay in the Body Answered

This is very important information. I asked this question and so far no one answered it, but I calculated it from what I have been studying and my PCP confirmed it for me, in writing today. Thus I want to share the information because I feel it is really critical to understand it accurately.

The half life of methadone is 36 hours:  it would theoretically take 5 half lives to eliminate from the body.  It is excreted by the kidneys.
If you stopped on the 18th, then the methadone should be out of your body 7.5 days later on April 25+.
Hydrocodone is eliminated much more quickly than Methadone which is quite long acting.

Not too terrible on the long term is it?
I am five days in and not dying, though it has required me to be very brave and focused. And admittedly I do not feel great yet. Still experiencing some withdrawal symptoms, but I expected it. Just sitting it out.

People on methadone - if I can do this, you can also. I am proving that it is possible. You only have to suffer for a few horrible days and you are essentially doing that anyway - 247.

Note: I am not an addict. I became dependent on opiates for chronic pain after a severe MVA and many injuries.
I am doing this after 11 years of taking the prescribed opiate pain drugs listed above by shear personal willpower. If I can do it, so can anyone else and you will feel better if you bite the bullet and take control.

I am happy to have this information as it helps me to focus on my ultimate goal. It has been confirmed as accurate by a medical professional, a primary Care Doctor with lots of experience.

Earlier she was irritated with me for going off too fast, but now she understands that I felt I had to get it over with. So communication is a good thing.

I have noticed that most of my physical symptoms have started to go away but my mental one are still with me. I have found myself to still be very anxious and jittery. I have slept though which made me feel a million time better. Two nights now in a row more then five hours and my bp is my normal again. I have hypertension from kidney issues. I also became dependent on them after just a short time on them for my medical issues. Thank you for the information.

Sleep is really important. I was hurting from fatigue last night but took a hot bath before going to bed to help me get to sleep. This works for me. You might try it, it is relaxing, you get warm and ready to sleep. Very pleasant.

I do not know a lot about kidney stones, but my father had them when he was about 70 and got them removed and then he was fine. Is that an option? he recovered quickly. (But he made us all wait on him hand and foot when he got the chance. ) Anyway, he became much more active after that walking and swimming every day and lost some weight. The surgery really helped him.

You might discuss this with your doc

Hi..I came off of a Methadone ride for 12 years and it was prescribed to me. Before that it was hydo/oxys and I did have a w/d from them too at one time. I did this 20months ago and I will just tell you that you can not go by a Book! I always say this to my DR. Like oh, were did you get this or that info from..A Book!!  Each of us are Different..Lots of things have to do with how fast you will bounce back and how long it will take. Like Taper compared to c/t..How many mgs in one day, how many Years and how Old you are and how Healthy you are, Diet & Exercise play a big role as well. etc.
It took me 10 days to go into wds and sleep was just none for 22 days and then it came in & out like small cat naps. The anxiety was on the moon for about 60 days and then I went into a very weak stage with no interest. I have and still am going through stages..As each month or Year has passed I can still feel the healing process. I have been using off & on since I was 14 and this here is why it does take about a Year or More for the Brain to balance back..Lots of Changes going on all the time.
NOW there are LOTS of people on this form that did go into w/ds earlier then I did and also bounced back quicker..Still it is a LIFE LONG PROCESS to keep pushing through.
CONGRATULATIONS on Your Time so far..Just take it day by day and except the changes as you continue to have Patience and give it the Time it needs to heal..

The hot bath works wonders. I added Epson salt and lavender to mine and it was so nice .  I have an appointment with my primary care doctor tomorrow and have a few questions for her. As far as the stones its more complicated then just removing them, I have had that surgery four times already. I only have one functioning kidney and my body produces a certain kind of stone. I have changed my diet now and changed a few of my other meds and am possible looking at one more surgery to remove a tumor.

Really watch your expectations, great advice above. Take it as it comes, anticipation and expectation can lead to disappointment. The withdrawals peaked at 7 days for me, 7.5 days sounds right. Then the recessed receptors in the brain are exposed and weak. Withdrawal is quick, relatively, but the healing still has to take place, just surrender to the process.

Sounds like a horrible condition. I am sorry you are having to go through this. I hope there is a solution. Best of luck. You are brave.
