I can claim in good conscience that I am a full pledge vegan. While I do not and cannot promise that I will be a perfect vegan, if such person truly exists, I could say with mostly absolute certainty that my position relative to that vegan ideal is relatively close.
My diet is strictly plant-based and I do not find it difficult at all. In fact, I am not even aware that I am being vegan round the clock as if being vegan is always what I have been. It just comes naturally, like breathing.
