Not me, I love what I eat too much.
I do have a close friend who's vegan tho but I can't answer the questions you've asked and have no wish to ask her about it. I admire her ethical stance and her commitment to her cause as she takes it very seriously, it's or I think it isn't easy choosing to be vegan, choices are very much more limited, take time to prepare and can be much more complex. Also living in a quiet area of the countryside it's not easy for her to find places that cater for her needs if she wished to eat out (pandemic aside of course) it certainly keeps her in shape tho, personally when I look at what she eats I feel there's hardly enough substance to feed a sparrow but hey, I'ma big eater anyway. As I say I truly admire her commitment and have great respect for that, it's just not a lifestyle I could ever see myself being able to live.
