I thought this thread was going to be a question asking about whether female users stop using during their periods.
There was a relatively brief period of time that I took time off to reduce tolerance and avoid addiction. At first it was every other day, so I never used 2 days in a row. Then it was 2 days on, 1 day off. Then less than that, and by that time I became physically dependent and felt so bad when I took time off that I stopped taking time off because I couldn't function.
Using opiates regularly is very risky. I think you need to be taking an equal time off for every period of time you're on, to avoid withdrawals. And I wouldn't do more than 3 days on at a time, max. Any more than this, and before long you're going to get withdrawals. And your tolerance will start to go up, fast, before you get withdrawals.
Also, once you've had withdrawals before, it takes a lot less to get them again, even after long breaks. And tolerance goes back to what it used to be after even like 2 days in a row. That's been my experience, anyway.
