I was vegetarian (no eggs included) for over 20 years and decided to go back to eating meat (still dont eat red meat) nearly 2 years ago. I was vegetarian because my parents went fully religious so never really did it on moral/ethics ground. It wasnt a massive deal, though I suggest you take it quite slowly as no doubt your digestion will have to get used to your new diet and please dont waste the decision by eating poor takeaway rubbish...
I only decided to start eating meat (its still a small part of my diet - might have it once a week - still dont eat it at home though) because it just seemed to be easier to get cleaner food (cleaner in the nutritional sense) and felt it would probably help as part of more balanced, healthier diet (vegetarianism is good for that, but I found it quite restrictive when it comes to choice, especially abroad, US especially - its quite easy to get into a rut too).
The weird thing is that I could quite easily go back if I choose to, I have no real attachment for eating meat, I just dont want the restrictions on trying new things though. Health wise I dont actually think Ive improved or suffered, just nice not to be an awkward guest or to have a poor choice from a restaurant menu...
