The good news for me is that I do not eat red meat, pork, or poultry (not vegetarian, just never cared for or craved it). I have seen that suggestion come up in other posts, so at least I can rule that factor out. The amount of refined sugars (soda) and dairy I consume though are a definite possibility.
I think I will give epsom bath soaks a shot as well to see if they help at all. Thanks for the suggestion! I wonder what Epsom Salt does/reacts with to (hopefully) help.
