Drug detox/fasting

Probably not much you can do for that without putting drugs back into his system.

Make sure he's eating good foods, proteins/iron rich foods etc. That should help with the low energy. But unfortunately, it's probably just going to take time. There's a reason why people don't stop drugs just because they have nothing better to do. It is quite the process that your body has to go through to withdraw.

Good luck.

Exercise will give him energy. It will also help purge toxins from his body. He can start small (just walking, for example) and build up. Plus, exercise triggers endorphin release, which makes one feel good without drugs (natural high/ "runner's high").

Ultimately, though, it is going to just take time. Wishing him luck!

It is a slow process and shouldn't really be done cold turkey. Is his counselors/doctors in the loop on this?? Below is from someone that has gotten off suboxone successfully.

"I have gotten off of suboxone successfully, albeit through many programs and done after one year on 75 mg of Methadone. The trick is to be comfortable at the lowest dose possible and then extend the time between doses, (and don't get tempted if you feel a little discomfort. Xanax helps enormously). Then, start cutting (dont break) the tablets into ever decreasing pieces while still extending the dose intervals by 2 hour increments. When you reach about 1 mg, take 2 last 1/2 mg doses 12 hours apart. The next day you will walk away feeling excellent. Stay away from trigger locations and people you used to hang with while doing dope. Find some friends or something to occupy your time for at least 6 months if not a year and you wont have any problems and will have lost a great deal of the urges to get high. It's a long process my friend. I went through it. But Suboxone is far better than Methadone which I was on for a year, and like you, I didn't particularly like being thrown in with the general population of addicts at the Methadone clinic every day. But never loose sight of the fact that you and I are addicts. We were born with a type A personality, and addiction to any substance comes easy for us. In closing, It's up to you if you want to be an addict for the rest of your life (and the longer you are, your chances of killing the monkey deminishes rapidly), or you want a normal life and to become a productive member of society and live out the only life you will ever have on this beutiful earth with the ability to stop and smell the flowers and the trees. It's a religious experience once you achieve it and you'll realize just what you have been missing. All the bad, guilty feelings go away, you can think straight, you can hold a job and experience the american dream. So try my method, and may God be with you."

I agree that some medical care would be a good idea.

Also, some light exercise. I wouldn't suggest anything heavy at this time, but just a light walk or stretch here or there will get his blood flowing and move things around enough.

Ask him to keep eating well, and unfortunately, things are just going to suck for awhile, but it will all be worth it.
