There are a lot of vacation threads, check them out...you have LOTS of time to make the decision. A few of us took a break and a few of us haven't (there are threads on both sides of the coin). Both sides felt very good about their decisions
If you take a break - you just need to put your 'head back in the game' as wuv phrased it. Or if you don't think you can do it, don't take the break and you can vacation while being OP.
14 weeks is a long time - you might be mentally stronger by then too!
