So I've been moving toward PB for a couple of weeks, but started in earnest on Sunday. On Wesnesday I developed stuffy nose/sinus symptoms and a swollen gland in my neck.

Coincidence or carb flu?

Otherwise, I feel great. I'm at fewer than 60 grams of carbs a day, not hungry, but calories are way down too.

Any feedback on the gland would be appreciated,
