re: Gumbo makes me feel awful - is it the type of sausage I’m using?

I'm not the kind of person to criticize another man's gumbo, but since you are asking, that is the darkest gumbo I think I've ever seen. It looks incredibly rich and strong, to each his own. But when it's making you sick when you eat it, maybe tone it down a little. As another said, less roux, and maybe a less dark roux, and the other suggestions already posted, less greasy meats in it.

It could be aging. I used to be able to eat a greasy rack of baby back ribs with no problem. Now, if I eat more than 3, I have to bring a bottle of pepto with me to bed. My body just can't handle the grease-sodium bombs like it used to. Same symptoms as you described.
