I have perfect BM daily but I also eat a fresh veggies daily. I cannot do any type of hulls/fiber or seeds so the veggies work fine.
I was craving sweet potato last year and it wouldn't stop until I had some. I think it was a vitamin A deficiency though since LC keeps me away from carrots and sweet potatoes/root veggies.

My favorite ones are called Garnet Yams, the small tubers are tender without the woodiness of larger sweet potatoes. I boil and mash with butter and they're divine!! Haven't had them since last winter but looking forward to buying them again when they're in season.
