 [ Symptoms ] how can i change the timing of a bowel movement from 5 am to a more convenient time which will not affect sleeping  this problem began after i started taking flomax for enlarged prostate even though i do not have to take to flomax anymore the 5 am bowel movement which wakes me up every morning has not ceased it has really affected my work since i rarely can go back to sleep until 7 when i used to wake up i am reluctant to take any laxatives because not sure of their effect on my system i am not constipated [ Disease ] you could try increasing the amount of fiber in your diet during the day along with plenty of water avoid eating a large meal at night have a larger breakfast and lunch your bowels are basically waking up before you want so this would be my best suggestion for a natural solution
