At one point of my life, I was a vegetarian -- no meat, poultry, seafood -- nothing!
Really what was your reason for being vegetarian? 
More from (what I perceived to be) health reasons. Not so much political, environmental, cultural....have you ever tried?
I haven't. I grew up on a farm so meat was a stapple for every meal. I think I would like it too much to give it up. 
I get that -- and actually follow the keto diet now. So I guess no veganism for you -- which excludes EVERYTHING, including eggs and dairy!
Yeah, I don't think I could give up cheese. I like that even more than meat!
I promise you that is THE number one thing that people find tough to give up. So hey -- you *could* be an lacto-vegetarian -- yes to dairy and a protein source ;-)
I think I could probably be a pescetarian.. I really like fish!
