The only thing I can say is how much sleep?
Like a little nap or one night will certainly make a difference, but it won't reset you.
A few nights then back at it will be incredibly good for you in many ways. Receptors will heal, tolerance will reset to a degree, psychosis will become less of a problem but I have been in situations of high stress where I've been totally sober. Then used a fairly average amount of meth and become instantly psychotic. This i attribute to the stress and possibly sub-par product. But psychosis will pop up at anytime, for any reason and sometimes for no reason and you can't do anything but stop and take a benzos/opiate or anti-psych and stay stopped for awhile. That's the reality of it.
