Do not believe I have posted in this thread before... but anyway, I became a vegetarian when I was twelve years of age. At the time, the primary motivation I possessed towards the change of lifestyle was to mainly be healthier, but as I further did research and learned what truly goes on with the slaughtering of animals and in which their life purpose was to be raised for beef, poultry, and such, ultimately I decided that yes, becoming a vegetarian was the most rational thing to do.
A couple of years ago, for an approximate total of six months, I attempted to be a vegan. However, making the transition to vegan basically resulted in myself receiving a lot of grief and trouble from family and friends, and additionally, as I still live with my parents and am not in control of the mass majority of the groceries brought into the household, it was simply not all that easy... I will also admit, going after little treats did become too much of a temptation, because even if something did appear to be dairy free, there would always be a hint of dry milk powder listed under the 'contains less than two-percent' in the ingredients.
The absolute worst and ridiculous thing I came across, which is off limit for vegans, was jelly bellies, because of the fact that they contain beeswax in their coating!
