I Sorry for my bad english, but it's a while ago since I had english lessons. I also live in Denmark and here we don't speak english everyday.
I too have the exact problem. It began when I was 14 years old (7th grade) when people started to notice that I smell. They opened the windows (also in the winter), said it always smelled in the classroom. My classmates which I sat beside began to move the chair to a longer distance and that irritated me a lot. Just to the facts, I don't think I was ever being able to smell it by myself, neither could my family, but everyone else could. Everyone besides my family (even my cousins). Later in years I found out that it just has to be an internal problem. Everything i ate had an impact to the Body Odor . In my normal days most people just sniffed. Some of them told me directly that I smell. Some of them I heard that the old others that I smell. And I'm 100% sure at least 50% in my school has talked about it. Lucky that I'm intelligent at school, very good to computer and one of the best in school in sports, and very funny, so many of them talked normal to me because of that. Can you imagine if I didn't had these abilities? About where the smell comes from: I sure it comes from the body and not from the butt. There are a lot to tell about this but I'm gonna skip it.
-MY (small) SOLUTIONS-
1. MAKE some sports! It helps like a hell. I play basketball to times a week and I sweet all the t-shirt while running, jumping etc. You sweet all the things that in the skin that makes the smell. But its just reduces the smell. In the sommer when I'm on vacation I usually don't play sports, and from there I'm 100% sure that its getting like 3 times more worse.
2. Don't drink alkohol
3. When you go to bath, you also have to wash you back. And don't let the soap be on your skin more than a few seconds.
A year ago I took a pill for relaxing my digestion system and I could hear a sound around belly that sounded like I was hungry, but louder and in a longer duration. The next day after taking it, people just couldn't stand be near me. I clearly remember that day. That was a hell of a day. Also at the basketball training someone stopped and said mething to another person, and that person looked at me while the other was whispering to him. But now you are mentioning the GlycoLax that do the opposite to that pill i was mentioning, rather to relax, it moves. I will certainly gonna try that one. Thanks a lot!
I will give you a notification if it helped. Thanks again for not just ignoring the rest of the suffers here, and took your solution with you.
