Irish, if you need help or ideas there is a veggie chicks forum with cookbook reccomendations, recipes, site reccomendations,etc.
If you start slowly by having one totally vegetarian day per week then increasing it to two etc. or by having 2 veggie dinner nights per week it may help ease into the transition it will also give you some time to research meat alternatives, find some recipes and make a plan for yourself so that you make sure you are getting the proper nutrition from your diet.
You usually end up experimenting a bit too - some vegetarian products are delicious and others are horrible. i.e. Soy chocolate milk for me YUM!
but soy chocolate pudding for me - YUCK!
