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

After having a consultation with my Oncologist, it was decided I have a 3 month break from taking Arimidex.  I will return onto the tablet in early December.  Has anyone found any side effects or withdrawal symptoms once the tablet was stopped?
Or had less or more joint pain and muscle pain once stopped?

According to latest studies I was informed by the Oncologist, we can have a 3 month break out of a 12 month period and it didn't seem to make any difference in terms of recurrences.

Also has anyone had a lengthy one block break from their AI? 
If so was there any obvious side effects? 
I also take a tablet for my hypothyroidism which also shares many of the known side effects applicable to Arimidex.  
  • @Cathyw thank you for your feedback.  I had a 6 week break in December 2018, and then went on Letrozole until about July last year.  Letrozole was not suitable for me with even worse joint and muscle pain, so I reverted back to Arimidex.
  • I had a month off as changed from Arimidex to exemestane. I felt better in that time, but sorry that's the longest period off AIs at this point.
