Hi there,
Surfer27 here. Yeah, i've tried the Citricel for my fbo before and it didn't have any good effect on me. Some people have suggested looking into taking Castrol Oil to help you evacuate and also to sleep well. The only other suggestion, I would make is to look at some kind of homeopathic remedy for anal fissures and fistulas, as fbo could be a result of anal area prolapsing, or could be a result of a fissure or rectal fistula. Just some ideas, you can look into, if your outta ideas :D. Take care and God bless.
