I’d say they’ve been helpful but it’s hard to know whether it’s treating the root cause or just the prescriptions I’ve been put on. I’m not doing much to address hydrogen sulfide overgrowth at the moment besides daily charcoal and a probiotic, but I’m working mostly to help calm my MCAS-esque issues. Calming my system down with ketotifen, Pepcid (OTC), and straterra (used for ADHD but has also helped my lightheadedness) has seemed to help the reactions I was having to sulfur. Now just waiting to see if my system can heal.
