Yeah sure.
The disease you were likely suffering from was mental. Being different wears on you and the micro aggressions of being a minority wears on you after a while. The food industry ads, cooking shows, bbqs, nostalgia, that random guy that says being vegetarian is dumb or deadly, etc. The mental pain builds up and causes the damn to break after a while.
I had a similar experience in the brief time that I went vegetarian. Plus I was skinny at the time and lost weight.
B12 deficiency stores can deplete over 2-4 years so it will be a while before you notice. You also need very small amounts (monkeys get their B12 intake by accidentally eating bugs on their bananas).
I tried going vegetarian for a period of my life and I started feeling extremely tired after a while. I stopped doing it mainly because getting protein is hard and I didn't notice any other positive changes.
Restricting yourself to expensive, high quality meat is a perfectly fair way of sustaining yourself and making sure the environment doesn't suffer too much.
If everyone only ate as much meat as they needed things wouldn't be so out of whack.
The unnecessary slaughtering of animals is a problem all by itself in my opinion.
> Restricting yourself to expensive, high quality meat
What about people who can only afford dollar menu quality beef?
> If everyone only ate as much meat as they needed things wouldn't be so out of whack.
A corollary statement from other threads are if only we limit population size meat would be environmentally viable.
