for those of you that have used the fisher wallace stimulator for pain --- I found a good solution (no pun intended) to use that helps conductivity. Saturating the electrode pads with Unisol instead of water. Of course, you can buy cheaper saline - which I'll do - but, I think that using saline that has the same salt concentration that is in water allows for good conductivity and also avoids stinging in your eyes in case some of the sponges leak down to your eyes by mistake -
