Your diet looks good - except the butter!! Light or not light, butter is DAIRY. DON'T eat it.
DON'T take something that you know "makes you go quickly" - this should be obvious! That's what the cleanse did to you! Something that "makes you go quickly" is just causing spasms, causing your bowels to evacuate. And now you know all to well what happens when you intentionallly cause your gut to spasm....
I'd say stick with the SFS you're using instead of switching around a lot. In general, no SFS is "faster" than any other. Just be patient. If the Benefiber is working for you, there's no use in upsetting your gut by switching to a different one.
