irregular bowel movement

hello everybody ... i m 18 yr old male and my irregular bowel movement is becoming a concern for me . the time for my bowel movements varies frequently from netime in the morning to that in the evening . this is surely disrupting my routine . i do drink lots of water and also take in fibres , however , to not much help . physical exercise too did not seem to help much .. i hope u guys do help me come with a cure for this . i have also noticed tat my sleep pattern too frequently changes ( 8 - 12 hrs )
