ONandOff hit it on the head basically. In order to have a significant lowering of your tolerance, a break much longer than 3 days will be necessary. I have detoxed in jail a number of times, and then used again once I got out. Even 18 days didn't lower my tolerance that much. It did indeed lower it, but then again after 2 days of using it went right back up to where it was before the break.
There is no free lunch with opiates. You got on the bus, and you've got to stay on for the ride. If you are prescribed them, I would advise you to just take as little as possible so you do not go into withdrawal. That way maybe you could save up a few extra pills so every once in a while you can take a bigger dose to try and get a 'high' out of them periodically. If you have benzos on hand, they are a godsend for the anxiety/RLS/insomnia associated with withdrawal.
It certainly doesn't sound like you want to stop taking them, so your best bet is just to take them as prescribed. Otherwise if you are trying to get off of them and don't want to kick them cold turkey, you need to come up with a tapering schedule, but your mindset currently does not seem geared towards obediently following a tapering schedule. Tapering will still have some minor discomfort, though. Personally I prefer to just do it cold turkey, I have always had the most success doing so this way. Tapering you'll feel mildly shitty for a long time, but ocld turkey is just feeling really shitty for 3-5 days. It doesn't sound like your tolerance is really high though so stopping codl turkey wouldn't be that bad, especially if you have benzos and buy some immodium as well.
