Without wishing to go into every boring detail, I went veggie in 1994. I'd never been a big meat eater, mainly chicken, bacon, sausages etc. We then got a smallholding and started keeping our own chickens, and I discovered how cute they were, how they all had different personalities and thought, I can't eat chicken anymore, it just didn't seem right. Also our neighbour grazed our field with her sheep and lambs. One day we were invited over for dinner, and she proudly told us that it was one of her lambs we were about to eat, probably one that I had petted and fussed only a couple of days before. That was the final straw for me. I stopped eating any meat at all from that day. After a few years, I got fed up every time we had something from the chippy, that was literally all I could have - bloody chips, they didn't do any veggie options here, so I started eating cod again or fishcakes, as long as there were no bones or skin, else that would be the end of my eating.
Years passed, and I split with my partner, and found that I could no longer be bothered to cook food now I didn't have to wait on another person, so I started eating mainly ready meals, healthy option type ones. However, I discovered that a lot of my health problems weren't being helped by eating quorn, mushrooms, pasta (gave me terrible IBS, wind, etc.) I ate plenty of fruit and veg, and had a healthy diet in general but I have had a B12 deficiency for years and years, before I ever went veggie, and also thyroid problems.
Anyhow, I decided to try some chicken again about 4 months ago now, and I found I could manage to eat it (I had tried bacon a few years back, and couldn't swallow it, I gagged!) So basically, I now eat chicken several times a week, I still eat veggie stuff too though, and have found my health really has improved. I've also managed to lose a stone in weight fairly easily over the past two months, so all in all, think I made the right decision.
If I stop and think about it though, I still feel bad about eating chicken, but my health must come first. I still cannot walk down the meat aisle in a supermarket though, that makes me want to vommit, nor could I cook a raw chicken, I can only eat ready prepared meat in sauce etc, not anything with skin or bones. Sorry if that's too much info!
