"Would brewers yeast, which makes your blood taste funny as outlined in thread linked below, keep mosquitoes and other bugs from biting you?"
I've never purposely tested brewer's yeast as a mosquito repellent; however, I have eaten plenty of brewer's yeast while camping out in mosquito-heavy conditions. (I prefer nutritional yeast for my cooking, these days, but they're both good. Try making pasta, and then using extra-virgin olive oil, hot sauce, black pepper, garlic, and yeast for the sauce.)
I'm not sure what kind of conclusions can be drawn from my experience, but I'll convey my experience to you. On the one hand, I always got far fewer mosquito bites than my lover. For whatever reason, she attracts a lot more mosquitoes than I do, probably in the range of 10:1. On the other hand, the mosquitoes were still biting me--en masse if given the opportunity. So brewer's yeast is obviously not entirely effective.
Now, camping with and staying near someone whom the mosquitoes like better, who will draw them all away from you--that might be the way to go.
