I'm working on making it so. I wasn't born hardwired to have a specific diet, so I believe I can make vegetarianism "for me" (i.e., become accustomed to it) over time.
I have coeliac disease, basically, if I eat anything containing even a tiny amount of gluten, my immune system goes berserk, and mistakes the gluten particles clinging to the walls of my guts for a pathogen, and of course attempts to destroy it with antigens and enzymes. This attacks the lining of my intestines and literally dissolves them.
So, a vegetarian diet, is not a realistic option for me. As most veggie products on the market, contain gluten, either in wheat or rye or barley and a number of other cereals.
It's a shame. As I would switch to vegetarianism. I only like beef and fish anyway. I don't like chicken or pork or lamb, and never eat them.
