I don't have any health problems, but I like to take care of my meals, especially eating healthy and varied, homemade food and not too much flour. Sugar hardly at all and not much salt either. I prefer to be as healthy as possible by choice, because I like it that way. And I don't suffer because I like what I eat, fruits, vegetables, meats.
Discipline is always the key, it is what guides us well.
One question, if you inject yourself with the stuff you mention, what side effect could it have on you?
