I have been using this product for over 15 years and all of a sudden I can't find it anymore. If this product is still in production, please advise where I can purchase it. Walmart, Walgreens, CVS Pharmacy, Rite Aid stores are not stocking it. I would like to know where I can get it through a store. I hate to purchase anything on line. I know it may come to ordering directly on line for this product, but if you could let me know, I would greatly appreciate it. Many Thanks, TJ.
