I;m so sorry your kids have been so sick… 🙁 As far as getting the GI tract working, if your son has symptoms of vagus nerve problems and/or low acetylcholine, Parasym Plus (2-3 caps first thing in the morning) would be the first thing I’d go to. The Digestive enzymes should be taken about 20-30 minutes before eating, and the Soothing Digestive aid should be taken when he starts to eat (you want to get the enzymes into his intestines before introducing the acetic acid). I hope it is as helpful for your son as it was for mine. Meanwhile, I hope you have a copy of The Driscoll Theory? All three of us (and others, of course) were able to avoid fusions by decreasing our intraocular pressure. Not everyone is as fortunate, but I see patients regularly who were advised to have fusions, but did GREAT with Diamox instead. Gentle hugs…
