Well, YESTERDAY I had fish. First time in over four years (volutarily) eating meat (save for an incident awhile back where a supposedly vegetarian quesidilla actially had small bits of bacon in it)- I'm giving up on being a vegetarian. It wasn't the bacon incident, I was planning on maybe eating meat before that and then a blood test I got a couple of months ago decided me- I'm anemic, and considering I don't get a period, I really shoudln't be, or not this much.
Are you eating properly at all though? Not getting your period is also a sign of being underweight. Go demolish some food....and meat!
I was a vegetarian for 8 years....then one day I was cooking steak for my boyfriend, I just started really craving meat....always.
Finally, a few weeks went by and I went to a work function, they had huge tables of spit roasted meats.....Seriously, I got a whole plate of meat and gravy....not a vegetable on it and sat down at a table. The guy next to me said 'you like your meat, do you?'....and I laughed and told him I was a vegetarian. Well....I devoured the whole plate and thought I would get sick, but I didn't. I've been eating it ever since, although, I would say, I'm not a huge meat eater....maybe once or twice a week.
