Being Vegan

Well, I have been vegetarian for quite a long time now.    Loved cheese and eggs and yogurt though, or at least I thought I did.  I started on a vegan diet this past Jan.  Wow is all I can say.  I have a lot to learn and have now become a food "snob"  or at least I feel like that.  I can not stand to eat things that are not plant based now.  I eat when I am hungry and not to "just eat"  I have lost 10 pounds (I have at least 20 to loose) and feel great.  I have energy and feel better all over!  Sometimes I have weird cravings, like olives (I did not even like olives!) and get "full" very easily!  What is it about this vegan thing?  I do find the reactions to my food choices from others very interesting.  So many people worry about me.  They seem to be focused on what I am eating more that I am. It is not too hard to eat like this but when traveling and at other's houses it does get a bit hard.  Any suggestions of what to say and do when you are a guest at someone's house? That seems to be the hardest thing for me right now.
