I feel this. I hope you get over the hump and your job gets fun. We've had flashes, at least, but I do think what we're doing (and probably what you're doing) require some irrational behavior.
I have a POC I'm trying to get out in a couple of weeks. It's for the #1 feature that was promised in this product, never possible due to the architecture, and we've gotten raked over the coals for it. Wish me luck, because if I can get it out soon, it's going to be downhill for a while.
