I am vegetarian (since birth) too… Initially it was based on religious beliefs, cultural and family upbringing….. Now, I am used to with it, personally, I am satisfied with what I am doing and never get temptations to eat or try meat and alcohol. Nowadays, I am vegetarian not because of religious and family and cultural reasons but due to health benefits and some kind of self-realized commitment to keep something that I have been doing so long. But the fact is that I am enjoying it. So, I never thought about abandoning vegetarian way of life.
