Alternative to fleet enema

I saw somewhere on here about someone who emptied a fleet bottle ( a good idea, they always left me feeling awfull ! ) and refilling with half glycerin and half baby shampoo, anyone heard of this or tried it ? if so what happened, im sure it would work, but was it too painfull etc ? im seeking a small amount of enema to force a diaper filling, and avoiding a litre or more of water that would leak everywhere.

I'd do half glycerin, tablespoon or two of baby shampoo and water for the rest.

1-2-3 enema might be what you want too. 1 part Epsom salts, 2 parts glycerin, 3 parts water.

Bisacodyl and soap might also give you a big kick from a small volume. Either use Magic Bullets or 2-4 (maybe more, but work up) of the 5mg oral tablets. Put a squirt of liquid Castile soap on them and let it sit for a day or so, then fill with water.

Almost every chain drug store or big box store sells their own brand that is virtually identical
