hmmmm, me too ! i rarely drink water before. only soda.
eversince i was young, i never drink enough water.
my bo started when i was around 14, at that time it was only sour smell.
the kind that you have when you dont take a bath only for me it happens say an hour after taking a bath.
about 6 years ago that's when i started drinking a lots and losts of soda everyday.
upto a point where i was feeling burning sensation every morning. that's when i also got from worse to worst. sour smell to fecal. yeast infections.
i'm 28 now so i've had this problem for 14 looong years. although now i know better and hopefully on my way to 100% cure.
of course it will take a couple of weeks to cleanse myself from all those years of abusing my body.
