That's excellent on your part! Well done. There are many people on BL who have been in the same boat. But your successful taper is really something to be proud of. I don't know how long you were using before you tapered, but at the amount you're at, you could jump off and be free in a few weeks if you're still on short-acting opiates. Do what you need to do and listen to your body, but don't let your mind make your task more difficult.
The only things I can suggest, since it sounds like you already have a motivation in your family, is to be as busy as possible. Work on your career, work on your art (incl. music, writing, visual arts, etc.), fix cars or bikes, ride them, go to the beach or the mountains or the woods, whatever. Get out of the house. If you have social anxiety, make it a non-negotiable demand that you have to get yourself out of the house to do something for yourself every day.
Schedule all of your activities. Try to make plans with people who don't do opiates or life-consuming drugs: go hiking or surfing or bicycling or play music. Start or join a band.
Exercise your ass off. Before my last back injury, running 5 miles a day + bicycling and walking were the primary ways I stayed as sober as I wanted to (just a little weed and a little wine. And I do mean a little.)
After many years of fucking with opiates, I still believe that my best highs were reached through running. I won't say that they were better than H, OC, or Dilaudid highs, but they were at least as good, and at least as powerful. I loved running way more than I ever loved any fucking opiate.
Exercise will be critical for you since your brain will still be sort of retarded in its endorphin-producing systems. Not only will the endorphins make you feel much better, but regular intense exercise (hopefully you don't have a CP condition) will get your brain back in the habit of producing endorphins on its own.
I'm not the best at prescribing diets tailored to recovering addicts. I eat very healthy and I know that veggies, fruits, whole grains, yogurt and lean protein will make you feel better and be healthier, but there are many other members on this board who can help you out with specific diets that include supplements. All of which will make the next few months a lot easier until you've gotten a little more used to living without opiates. Kombucha (GTs is the best commercially available IMO) is an excellent thing to drink when you're feeling a lack of energy. You can also make it yourself.
If you have the dough, acupuncture and acupressure are amazing for getting rid of cravings and providing highs of their own. I wish my HMO would get it straight and provide those services.
Keep yourself engaged. It's not my thing, but if NA/AA works for you, go to meetings.
You can definitely do this. Many congratulations and I wish you the best in the net few months. Post when you feel that you might cave in to cravings. There are a lot of ppl on here who have been through the same struggle, and who continue to fight it, so post if you feel you need support. It's a hard thing you're doing but very much worth it.
