Fourteen years ago, there were my own money troubles, so that I was needing to get food where there was help for that, this made a difficulty in going vegan when I might have otherwise. Going vegan itself right after that difficulty was not hard, I can give tips for that.
For me, the process of becoming vegan was hard during the first few months when I was craving my usual diet. But the craving faded over time. Our body and taste adapt real fast. Before becoming vegan, I would hate an all-veggie sandwich. But a year later, I would love it, especially with a good dose of yellow mustard. It’s also interesting how I started to notice nuances in flavor that I had completely missed before. Like I can notice small differences in seasoning or spices that I was oblivious to before becoming vegan. Being vegan is even easier, at least for me. My main food base is brown rice and lentils. That’s where I get most proteins from. To that I add cereals in the morning, some pasta, and a ton of vegetables with lunch and dinner. How difficult is that? As far as supplements, I occasionally take B12 and Omega 3. Fifteen years on, blood tests show I’m doing ok. Not sure about the choline issue talked about in other posts. But I guess everyone reacts differently to different diets and what works for one may not work for somebody else.
