Went to three different drug stores the other day, looking for an enema bag. Not only did they not carry them, the druggists at two of them didn't even know what an enema bag is!
They are hard to find. I like the bulb enema myself. For me it is easier to handle. Here are a couple of websites dedicated to enemas (CE in particular). I am getting ready to purchase something from them shortly. I have purchase from SA Wilson's but not the 2nd site I listed.
Yes, it's true-like the older glass-mercury fever thermometers, now relegated to history's garbage dump, it is extremely difficult to find enema bags, be they fleet Bag enemas or the Fountain Syringe style. It does take a matter of looking though. And should that fail, there are web sites dealing with enemas and the purchase of related equipment.
