I’ve been using a biofeedback device lately which requires an electrolyte solution to be applied to help the parts that attach to my skin to make contact. I’m running low on the solution, and it’s not so much that the replacement stuff is ridiculously overpriced, but it seems like a pain in the ass to have to go through all the steps of ordering it by mail.
I’m convinced that there’s something in my local pharmacy or even supermarket that will work just as well. But I’ve asked a few pharmacists and tried a couple of search engines with no luck so far.
Any suggestions? Thanks.
