Are you bloated after meals? One thing that I’ve found that’s helped with my stomachaches and bloating is betaine HCL. If you’re not already supplementing with it check out this article: http://scdlifestyle.com/2012/03/how-to-supplement-with-betaine-hcl-for-low-stomach-acid/
Another possibility: I used to get really bad cramps after eating inorganic meat. Chicken, beef, it didn’t matter. Something to consider.
Also, I’m very interested in the probiotic deodorant you mentioned. Do you have a link?
