There was a thread about casting one's own suppositories by melting Fleet's and then using a rubber glove as a mold. I've done that, in the past, with really no more benefit derived than just inserting multiple suppositories in the original configuration. I have also tried using glycerin, in its natural state (liquid) and adding gelatin. Had some limited success, but tough to administer (they didn't hang together too well). It's the stearate in the Fleet suppositories that allow the glycerine to solidify, so I postulated that there is probably more than enough stearate to handle a larger volume of glycerin and have the side benefit of lowering the melting point. I melted down some Fleet's and added some liquid glycerin to increase the volume, and then poured this into a rubber glove stretched over the mouth of a glass. Put the glass in the refrigerator for about 40 minutes and the result was beautifully smooth, large suppositories that were more gelatinous then the original - more slippery also. Tried one this AM and it was amazing. Held for one hour, it totally liquified and cleaned me out as well as a small volume enema. Just thought I'd share.
