Here's another thought. You could try it once -- wait an additional 1 -2 weeks after the 11th week. If it feels like a vacation from the w/d -- you still get to decide whether that's worth it to you or not.
If, however, you continue to feel crappy, or even feel worse -- then it means you're in poop-out and you're not going to get a benefit from going even slower. Then, you just have to soldier on at a survivable pace with no expectation of getting to a neutral patch before the next drop.
