Having a break from Arimidex / Has anyone experienced any withdrawal side effects?

@arpie, good to hear the magic oil helps.  My joint pain has not subsided since having the break from Arimidex from early September.  I may as well just go back on it when the 3 month break in early December ends!  Can't be certain, but I think the AI's have accelerated my osteo arthritis condition in many of my joints.  Oh the joys of living in discomfort and broken sleep!  
Last year I trialed Letrozole for 6 months, and that was the worst and my joints never seemed to recover from that.  If only I could stay positive like my name suggests..... wishing thinking I guess.
