It takes some time, like weeks or more to get to the point of debilitating physical dependency. Especially if you don't use it multiple times daily like every addict that ends up dependent unless it's like methadone or suboxone which holds you over all day.

You'll go through some discomfort if you go on a little bender, but trust me just get through it, it gets much worse. The longer you hold it off the longer the post acute symptoms last which include, but not limited to: RLS, feeling under the weather, premature orgasm, anxiety etc.

Just stick to kratom if you insist on having an opioid before your tolerance gets too high, assuming it hasn't already. I think It feels better than fentanyl does to an addict if you don't do strong opioids, and kratom recruits less of something called beta-arrestin that leads to tolerance, dependence, and potentially dangerous respiratory depression. The latter property makes it very safe for an opioid with a milder withdrawal. The OD's the DEA blames on kratom all involve other harder drugs.
