i think you should take as need to. there is no real set time, listen to your body and it will tell you what it needs. eat, sleep, and just chill out for a while. i used to take these 1 week breaks every once in a while, but keep getting burned out.
i then stopped for the volleyball season, and now that i've come back 3.5 months later i feel better than ever (gives my tendons a rest too, jesus christ all that hardcourt and constant plyo feeling) and am gaining quickly.
i'm not saying go take 3 and a bit months off, but i mean, take as much time as you need, in fact, take a little bit more because it's not like you're on a time limit. think of it as recharging those batteries, you will come back stronger than ever (not at first though haha).
