Jeez, sorry about your bad experience, and I'm glad you're ok, but there is no reason why this should have happened. Why would you use phosphoirc acid? Let that be a lesson for people, don't sue phosphoric acid for ayahuasca. The truth is, a lot of people don't use any acid at all for ayahuasca, and claim equal potency. It's not worth it ingesting strong acids for a tiny amount of extra alks you may or may not get from using acid. Furthermore, when one uses acid, not a lot is necessary. You don't need a half vinegar brew (and note that store vinegar is only 5% acetic acid and 95% water, and it still has a ph of about 2.5.)
But, if you do want to use an acid, there are 3 perfectly safe grocery store acids to use. Vinegar, citric acid, and ascorbic acid (vitamin C). A vitamin C tab should do just fine for a brew, and it won't burn a hole in your stomach. It's meant to be ingested, pure phosphoric acid is not.
I won't disagree with your idea of checking the ph before you drink, but man, if you just used a pinch of vinegar instead this wouldn't have happened.
The problem probably stems from a notion that people seem to have that stronger acids are necessary for good yields in extractions or brews. Well, let me just say, there is no reason to use hydrochloric acid, or phosphoric acid for extractions or brews. Vinegar or vitamin C work just as well. Heck, some people are getting 2% yields from stb.
