Hi there -
Xanax just works quicker in the body, entering and leaving rather quickly while klonapin may take a bit longer to 'work' it stays in the bloodstream longer. As long as your own doctor gives you consent to switch back, I can't see any reason for needing to 'wean' yourself off xanax - unless, of course, you feel more comfortable changing meds that way. Just remember to keep your physician in the loop! Take care now ...
