FTR. I take aprox, 10-16 drops three times per day and I have run numerous stop/start cycles over the past 1-1/2 years without any issues. However(on the other hand), my own bottles of MMS never last more than a couple of months in total so I really can't comment on the possibilities of long term storage.
Having said all that... I can say that I have grown completely intolerant to the taste and smell of MMS :(
I take it in capsule form now and I've devised methods to completely mask the taste and smell. Otherwise, the very thought of it makes me want to hurl in the worst possible way.
Hope this helps, and good luck on your path to wellness.
