I personally don't think you harmed your gi system with them although I can't personally say for sure, but behaps altered it some. Your body can get use to relying on them to go and that may take a little while to go back to more normal again.
The sensation of incomplete evacuation is a common symptom of IBS and a symptom that candida infection would NOT cause, which is one reason we don't see eye to eye on this as there are a specific cluster of symptoms to IBS and ones that support the diagnoses of IBS.
However, just like biofeedback traning for the bowel the bowel gets use to things and even times you go and you might have knocked it out of balance and possible and I say possibly made the IBS act up more then it was before.
There is a famous IBS doctor Named Dr Michael Gershon who wrote the book the second brain. He was mentioning a DR working in the army with people who had bowel wounds. The Dr left and the new doctor was surprized to learn all of them had to go to the bathroom all at once at 10 am. They had all been trained to go then.
The colon in IBS contracts abnormally along its length and this traps gas and causes abnormal gas transit, instead of it coming out normally.
Gas in IBS is a hard symptom to treat. helping the colon move along helps, even relaxation can help this, so the bowel muscle contractions are not so strong so to speak.
The sensation of incomplete evacuation in IBS is because the nerves there are sensitive and send signals to the brain, even when there is very little or no feces in the rectum. This is in part neuorlogical signaling between the two, that is how your co0nciously aware you have to go.
are you taking any probiotics?
Because of the candida issue, are you doing anything else in that regard, taking anything or trying to kill anything?
That may or may not be imortant on the gas aspect.
