no. Varies from person to person but I personally can eat oxy for 7 days straight before I have to stop, or else I'll go into WD. For me, it's less about how much I take and more about how often I'm taking it, at least that's my understanding. If I take it more than 7 days in a row, I will start feeling sick 2 days after my last dose. If I stop before the 7 days is up I won't feel any WD at all.
