That definitely is a fear - I can totally imagine how upsetting that'd be for you. I'm glad you shared it here because it could help other people
For me personally, I'm having problems with overly hard stools, but I've found they're a lot bulkier when I have metemucil (I bet youre already trying this).. I can see how much it'd suck to have a loose BM - I just had one and it was burning quite a bit, I think I somehow tore my fissure YET AGAIN (there was blood, I guess a lot of blood means a lot of trouble?)
Anyhow, are you taking metemucil? (not sure if you mentioned this yet) - i think that'd help. All bran as well like Kim mentioned. I think you just have to get used to your body and how it works and you learn what's good with time.. Take care

God Bless You Sheri. Hang in there I'm sure it will get better! It makes me wonder if the botox also effected your external sphincter. If so one good thing is that it is temporary.

Hang in there!
