DMSO and metallic taste

Hi...been using some DMSO 70/30 solution on my temples and neck.  I had put it on for about 15-30 mins twice a day for 2 days and the 3rd day I could taste a metallic or even a taste of the DMSO in my mouth.  Does this mean I used too much? or maybe its working?  thanks

DMSO penetrates deep, so tasting it sounds like a normal reaction to me. 

I really appreciate the responses. I haven't ingested DMSO yet but I use the aloe vera 70/30 mix bought from amazon and Im liking the results. I think the metallic taste was just in the beginning, maybe it was a sign that it was working?! who knows.

I actually rub the DMSO cream on my neck head and temples and then ingest 7 drops of CDS. I feel thats the sweet spot for me.

Very much appreciate your insight. Does Andreas Kalcker have a DMSO protocol? Ive gone through most of them but cant remember. What would consider to be the most optimal DMSO and CDS protocol? If im doing it, might as well be right!!!

Protocol-K by Andreas Kalcker is for topical use using CDS and DMSO. 

Protocol-K is attached to this message, plus a PDF file about DMSO water dilution is also attached.
