Depends on what you are trying to combine.
Sure, we've done abx with various supplements, FCT (failure), HBOT and mHBOT, various herbal protocols, anti-yeast, heavy metal detoxifying, etc etc etc. And so much more.
Not ALL of these at the same time, but sure, we did more than one thing together.
We did the Burbur/Pinella during same time period as some of Buhner's herbals. However, I wouldn't personally combine the full Buhner, Bryon White, Beyond Balance, and Cowden protocols together because there would potentially be some overlap for sure! (That's not to say you couldn't do some parts together, but that would need to be researched carefully. Similarly to how you combine abx together.)
Kid#1: Extremely sick for several years, very difficult to treat, but doing great now!
Kid#2: Very sick now despite being treated for years, still very bad
Kid#3: Generally good but relapsing off/on.
Me: Adv Labs positive 2016 (suspected I passed to my kids)-not as sick as others, mostly battling fatigue and yeast issues (heart/kidney issues resolved)
Treating with herbals now.
