If money allows, try a Naturopath. They are expensive but I know I was personally spending a lot of money on scented products, herbs and special dental equipment to try to solve my problems before getting guidance from someone more knowledgeable and objective. I've had two visits with mine only to find that it may have been a toxic liver all of this time and not all of the other things that I thought it was(and was treating myself for).
Good luck to you! Keep a food journal if you haven't already. I find myself looking back at mine all the time. Also, Elimination Rotation Diet may be helpful too.

Hi, You said you don't see a point to see a doctor but actually there is. Doctors has accesses to test and also can help find out what condition/disease/etc you have. I think it up to you to find out if that conditions/diseases/etc is the cause of your odor. For example, I have gone to the doctor but never told him about my odor problem and i don't intend to anytime soon. What i found out Is that i have diverticulosis and recently they got inflamed (diverticulitis). I have external and two internal hemorrhoid and a few Polyps. you may wonder what does this have to do with anything. Well, the the food i ate and my non active lifestyle cause theses problem in my colon and rectum area. and it also contributed to my b.o. Conclusion, if i have not gone to the doctor i would not have known about all this helpful information.

Also, you don't have to go to a gym to exercise. you can do it in your own home without equipment. Things you can do: Run in place, push up, sit up, dancing, walk around the block, etc. be creative!

What do you mean your diet is good? Did you cut out all process and junk food? do you eat lots of veggies and fruit? drink lots of water? I know it hard to cut out all the food you love eating but we must make those sacrifices Anyways, Good luck for now!

"However reading the stories on how others doctors were no help. I kind of don't see the point." You don't know until you try. You have to try. You have to be your own advocate. We've all had our share of pity parties, but there comes a time when you have to dig down deep and start helping yourself. You can choose to stay down, but know this; life goes on with or without you. So why not give it a try? You have insurance, go to the doctor.
