i feel your pain man.. i had/have this problem almost as long as you had..
mine started as regular sour smell.. it just got worse to worst..
dont know how i smell now.. a mix of sour/cigarette/coffee and fecal
had this long enough i kinda given up.. i use to be regular
in curezone.. now i just visit once in a blue moon.. just to read..
dont think there is anything more to try.. i had tried almost
right now am taking probiotics.. high is bifido.. not acidophilus..
i read somewhere about a test regarding this.. my hopes are low
for this though..
honestly, i am a peace with this already.. of course am stll hoping..
but am no longer as crazy with this as before..
gudluck to you all..
Lord, grant me the serenity to accept things i cant change..
the courage to change the things i can..
and the wisdom to know the difference..
