Is it easy to go cold turkey ??
If you're sick of meat, I'd say...yeah
You might want to do some reading about it. The China Study might be a good resource. I'm not entirely convinced it's the way to go, but they make a good case for veganism.
He eats a lot of beans, rice, tofu (nasty stuff), veggies, fruit, whole grains, if he is having a busy day he will make himself a protein shake, using a plant based protein powder, he eats cheese, drinks milk, eats ice cream,yogurt,he eats no more than 4 eggs in a week. He has tried a lot of the fake meat stuff you can buy, some has been good, some not, his favorite is a vegetarian ground beef stuff, it looks like cooked ground beef,add it to anything that you would normally use ground beef, comes in the frozen section,some of the frozen meatless burgers he has found that are okay, he has found the chicken stuff to not be very good, except for some fake wings I found for him one time, he has tried the fake bacon and lunch meat stuff, he didn't like them. Walmart here in Canada carries a lot of different vegetarian frozen foods. I have found with him it's all trial and error.
The hardest thing that I have found is going out to eat at a restaurant, he usually only will order a veggie omelet, or a build your own pizza. He is very anal about getting any animal protein, as he says it will make him very sick, because he hasn't ate meat for so long, he gets concerned with cross contamination,
And she loves Trader Joe's meatless meatballs.
Nobody forgets what happens, the secret is learning to live with it.
Where it is difficult for me are the two kids in my house that do like meat, and I'm not going to push them to be vegetarian or pescatrain unless they want it for themselves. I think my son could do it, he eats like I do.
I live on dairy (greek yogurt/fruit/honey for breakfast) salads or left overs for lunch and dinner is generally healthy, whole grain and "clean". Tonight's dinner was brown rice, teriyaki salmon, and a salad. My kids wolfed it down.
I don't eat tofu and I don't eat the meat replacers and they are filled with chemicals, or the ones I've found.
Chocolate and icecream still go down just fine...as well as mojitos
I have, over the years, lost about 70 pounds since the birth of my son, when I put on that 70 pounds. Some from the infidelity diet, the rest from just eating better.
