Breaks are healthy in any endeavor. Normally I'd suggest pushing through writer's block because most people don't actually write that much, but it sounds like you're writing regularly, so I think a little break wouldn't kill you. That said, the following lines make me think your issue isn't (just) writer's block. 

[quote]Should I just force some writing out, no matter how bad it may be...[/quote]
[quote]I can't reproduce something of that quality right now...[/quote]
To me, that sounds like editor's block. I think you need to cut yourself some slack, separate the writing process from the editing process. I highly recommend giving yourself the freedom to just get the words on the page, even if it's garbage. Don't be afraid of failure. Fail often. Take some pressure off.

Anyway, here's a tip I've heard but have yet to test: if you draw with your left hand for a while before writing it helps stimulate the right side of your brain.
