I use both the Sea Drops and J&J. NO not at the same time (geesh). I have both in my available and what ever I grab is what I use. Though once the drops are gone, it's unlike I'll buy more J&J (Baby - easy on eyes) is cheaper and works just as well. I have it in a small bottle which can dispense just a drop or two at a time. I don't dilute it at all.
