I still eat veggies. They are just a side dish now instead of being the main course.
Nowadays I try to eat a more traditionally "balanced" diet. I eat a decent amount of meat and dairy and eggs in addition to grains, legumes, nuts, fruits, and vegetables. I then use basic portion control to control my caloric intake and my weight.
It's been almost a year now since I abandoned pure veganism and switched back to a "normal" diet and I haven't had any more occurrences of kidney stones (knock on wood).
