So hard to find these days except through sources. Most of the easy one click buy options are gone due to RX labeling. I searched over an hour and a half today only to find that you need a doctor's license/health license or they're sold out. UGH. I even contemplated on making my own... Hmm.. maybe I should be the BAC source.. lol. All kidding aside, I finally found a sht ton of them on ebay.. Just hope the water is still good with exp. dates
