We seem to have similar metabolisms. For a long time, I had to avoid anything even remotely related to sulfur, including selenium, thiamine and multiple other supps, and MSM and DMSO, which I used on a painful knee followng a slip-and-tumble on the stairs here. It did close to nothing for the pain, and launched me into a world of exhaustion, anxiety, and multiple other bad responses.
Back in 1995 I had a bad allergic reaction to septra, hives, itching the whole bit.
As it was the only antibiotic that was working on a drug resistant infection, they brought in a specialist doctor that controlled the dosage to where I could continue on septra treatment.
So when the literature said there's no connection between sulfa allergies vs sulfur or sulfates or sulfites I am skeptical.
Right now I'm taking plenty of molybdenum after starting on taurine and green tea extract to see if it helps my lipid issues.
Fwiw about DMSO, I found from experimenting that it mixed with skin lotion and either coq10 or the contents of Advil gel caps helped with muscle pain.
I still do it if my ankle starts acting up.
The mysteries of why which does what still elude me, but I've become much better at noticing reactions and pretty much knowing what to cut out to test what's causing them.
the fatigue I got 2 days after starting the thiamine was from phosphorous depletion caused by the thiamine, due to refeeding syndrome.
Mysteries is right
In the past I've had temporary cessation of symptoms from thiamine and also l-lysine and I still wonder about why they helped for a short bit.
Retrying them later did not repeat the improvements.
I've had middle of the night insomnia for a couple decades now, when I was working a dayshift job almost 15 years ago I went on Ambien CR and proceeded to lose close to 30 lbs over two or three months.
Went off it a few years later and slowly gained the weight back, retrying Ambien again did not lose weight
