Not to mention voluntarily installing some of the worst spyware...
It's about personal responsibility. I'm not an expert, and I'm not going to pretend to be--especially when it comes to someone's health. I feel like it's important to make an effort to avoid misleading anyone.
It's also a good idea to talk to your doctor when you have quetions. I've consulted my doctor about supplements, water intake, and all kinds of seemingly innocuous things. When it comes to my ADHD, I talk to my care team regularly about the stuff I'm doing/not doing.
