Hey - to be absolutely blunt - do you suffer from constipation or diarreah - if you have BO problems it could be because of basically food putrefying inside. My bro had it and changed his diet and amazingly he smells sweet!
Write back if you do and I'll give you what he did - I've posted it up before but on here its hard to find old messages!!!
Remember you have a symptom, not a disease - which means you can get rid of it with the right method!!!
Have faith in your bodys ability to heal itself (sounds wanky, I know!lol!)
