I think that is one of, it not the most, strangest and most thoughtful questions ever posed on here!
EDIT: I hope you get or see this again. My above answer was because I thought you were making this up. Then when I saw a response from someone about PICA I did a little research. As someone said it could be a deficiency in our body. I searched several other sites and many of the people who eat soap found out they were anemic and there body ws lacking iron. After taking iron suplements it helped them stop or at least cut down. It didn't help everyone but it did help some.
I've just copied a post from one person from another site for your info and for outhers who have this affliction to see.

I never thought there would be any blogs of people eating soap..I googled it to be curious cus I have problem eating soap myself..My fav right now is Dial tropical escape..I have ate other soap before just aabout anything that smells good..I like IVORY,IRISH SPRING,COAST,and other DIALS..I even collect soap from hotels and i take soap from everywhere ..I always wondered why and if there was any health problems with it and i always thought there was but its hard not to eat it..I think I started when I was pregnant with my first daughter..Shes 5 and i still do it through all these 5 years even through my pregnacies with all 3 kids..Its weird cus i could relate with some of u like how i eat it when i get stressd out or just plain out crave it..Esepcially when i get into a big argument with my husband or when my kids drive me crazy..I sneak to the bathroom to pick at the soap and i have some hidden in my bathroom cabinet from my husband and im really embarassed about it..My daughter asks me what im eating and i lie and tell her its candy..I ripp some of it off and put it in my pocket to pick at when im around in my house,on the road driving and at the stores..pretty much anywhere...When i go to the bathroom i grab a bar of soap and lock the door from my husband and start scrapin at soap that hasnt been open and i save it and scrape it whenever i go to the bathroom..my nails hurt from pickin at it and i get sores in my mouth and it hurts to brush my teeth..I sniff the broken pieces of soap too and gets in my nose and burns and sometimes it burns my throat..It also gives me that satisfaction like im sniffin drugs cus i use to smoke meth and snort it 5 mos before i got pregnant with my oldest which i only did it for a few months..And I even cut it up like drugs too..I remember at first id lick the bubbles when im in the shower and just to bite the soap to leave bite marks..I have quit eatin soap for awhile and i always tell myself that i'll get sick..I throw away the broken pieces i made with it and leave it be for a few days then i'll go back to doing it again..I went without the dial soap for awhile cus i didnt see it any stores that i went to but i found it and could resist..ANd when i do go to the store i have to go by the soap aisle and sniff the packs..I hate it!!! I know its ruinin my teeth and and its ****** gross..but it tastes soo good..I like how it breaks up in my mouth when i chew on it into pieces.. ANYWAYZ! BUt thank u all for postin cus i thought i was the only one and now that i know what the disorder is and realized i could have anemia and lackin something im gonna get ahold of my doctor and let them know..im not embarassed about it anymore..ANd to all u ignorant punks, grow up!
