Dont force yourself to drink that Much water in a small space of time.drink when you feel like u want to drink.but make sure by the end of the day uv drunk enough water.
Thanks @october baby I guess thats wat I did jus drink it too fast its like I was tryna hit a target... yap ur very right.
Sometimes if I drink water too fast ill throw it up or I normally drink a lot of water but sometime I over do it and throw up.. drinks lots of water but dont try too hard or drink too much fast
