"Don't think about what you're giving up! Nobody likes to "give up" anything, look for the positives of eating vegetarian. The amazing variety, tastes, and nutritional value in vegetarian cuisine is astonishing. Explore! Find your favorites! You will find that just having the intention to go towards something better for you will let the old habits fade away.
When you have a vegetarian meal, use your senses to fully enjoy it. Feel the difference of eating vegetarian that comes in time: the lightness, clarity, ease of digestion, clearing sinuses, uncoated tongue, and if you're using spices correctly you should also notice stronger immune system.
Getting clean of all effects of meat takes quite a long time and produces a real difference in how you feel and transformation in how your body deals with food. If you find that after awhile you have a craving for some meat, take some, don't fret about it. You're probably not transitioned fully yet. You'll get a reminder of what it was like by the effect. I still like the smell of bacon after 40 years but I wouldn't eat that greasy stuff again. Hot dogs and burger are a disgusting smell to me now, and even just a modest amount of meat could actually make me sick. I know, someone snuck some in once, said it had no meat, but it did.
Do not give up dairy products (well, except old hard cheeses and highly processed stuff). You need the calcium, fat, and vitamin B12 dairy provides. Otherwise you should take B12 supplements. And the fat is needed for the brain and other functions which meat had been supplying. Remember, you started out life with milk (if you were lucky), dairy products are not the same as eating meat. Eating meat and dairy together is not good. The Jewish prohibition of mixing the two has some basis (no I'm not Jewish). Favor fresh dairy. Also take "probiotic" products like yogurt to help build up your good gut bacteria which is synergistically important for absorption and assimilation, especially when so much food is contaminated with glyphosate and other pesticides that kill good bacteria. Organic dairy is best, it won't have the awful rBGH hormones in it.
You should know that even conventional grain crops are now being sprayed with Roundup (glyphosate) just before harvest to uniformly "ripen" (kill) the plants. That means there is really little chance to wash off the pesticide residue, it goes right into the mill, into the flours like wheat and oats and barley that go into cakes, donuts, cereals, and so much more. The World Health Organization recently declared glyphosate as "probably carcinogenic." Organic is a far safer bet.
Be sure to explore the world of spices and how to use them properly. Meat dishes use very few spices whereas vegetarian food has immense variety and possibilities. The best place to look for spicing is Indian vegetarian. It's a garden of delights and has a long tradition of knowledge of their benefits. Spices supply not only tastes but also nutrients and unique chemistries that can actually boost your health and help with absorption of nutrients. Fresh ginger—marvelous stuff. Turmeric—miraculous benefits! Cumin—gets your appetite fired up. Fennel—sweet digestive. So much more awaits you. There are many Indian styles of vegetarian cooking and many cookbooks and resources. I've used the Hari Krishna cookbook. I don't recommend their chanting practices or religious beliefs but they sure do know good Indian food.
So enjoy yourself going vegetarian. You'll soon enough forget about craving meats and eventually will find meat disgusting even without thinking about where it comes from, or the price."
And I agree with you here.
