your body will adjust to the bathroom visits. i down about 2 gals a day, feels good, feels cleaner, you will notice you feel more energized, removal of waste from the body is smoother, of course your bm(s) will be better
etc. epecially if you work out a lot or play a lot of sports you need to drink plenty of water.
that girl died because she didnt go to the bathroom. as long as you go, you wont die from drinking too much water. water intoxication is from holding it in over a period of time and drinking lots of water.
