I took breaks several times on Fiverr and never noticed any significant dropping in my stats long-term. The only issue I encountered was that there seemed to be an error if I set my status to unavailable on the desktop version and then didn't restart my mobile app. In such cases, I was still getting messages, which was disturbing sometimes. Other than that, all the stats came back to normal within one or two weeks after a break. I must admit, however, that I never took a break longer than 7 days.
