I was as puzzled as you. Was it my clothes? I started to change everything every single day.Was it my skin? There is no antibacterial soap and shampoo I have not tried. I even went to the extent of equipping a small storage area that had a sink at my job, so I could clean myself up at mid day. I would have a sponge bath at mid day, I got a mini fan to help me dry off in a hurry, I equipped it with antibacterial wipes, deodorant, toothbrush and toothpaste, body powder, and body sprays. Imagine the stress everyday of wondering when I can sneak off to wash up. I set up every kind of air freshener in my work space (it was a large room), and still... most disheartening. It took a long time for me to understand it had nothing to do with hygiene practices. But at the time that's the only thing I knew to work on. After years of struggle my conclusion was it had to be a metabolic problem that was causing me to give off these odors. Read up on metabolic causes of BO and see if there's one that best relates to you.
