Bummer re: the chelating, sherry. I do the methb12 because I have no intrinsic factor, which is necessary to extract b12 from foods or the cyanocobalamin.
The baby bottle protocol works for those who are very sensitive - and it does eventually get you to 3 drops an hour - but the consistency of the dose over the 8 hours is what is most effective. Michael Harrah used DMSO and he said it settled his stomach issues - and I used the baking soda addition and it allowed me to tolerate the 3 drops/hr dose. CDS also worked for me.
You may be experiencing reactions to parasites - just as a thought - when the new parasite protocol is released, you might look at that.
