I have been taking 0.5-1mg xanax at night for years to sleep. I only take it at night and don't feel anything if I don't take it. It has a very short half-life for a benzo and if you only take .5 once a day, I wouldn't expect you would have any withdrawal symptoms. The opiates are the butt kickers. All I know is I can go without the xanax when not needed with no ill effects whatsoever.
I took like 2x 2mg xanax a day for 7 days, with 2x 24hr breaks in that week, and I felt noticeably worse (especially the restlessness) than I had the previous days. I am on day 3 with no xanax and day 12 with no opiates and I can feel the xanax withdrawal is almost gone by now.
Agreed, particularly if you can go without some days ... better to space them out a bit.
That's the intended use for the drug.
You should have no problem stopping....
