Update: well, it's been a week. Since I started about ~70-75% of my calories have come from sweet fruits. The rest have come from vegetables, vegetable (non-sweet) fruits, oats, rice and soy milk. Yes, I've eaten a lot of fruits.

I haven't been counting calories but I counted them afterwards (just now) to get the rough numbers.
So far I've experienced...
[*] bloating/initial weight gain (it should be mostly/only water)
[*] much more energy and endurance when I run outside, I'm more active, less tired, generally more "springy"

[*] every single person who's seen me has said I look better and healthier!
[*] it takes your body time to adjust to a new diet, no matter what it is
[*] fruits
can cause cravings (of more fruits, at least for me

)
[*] switching to fruitarian/raw vegan will have effect on your toilet visits
I've tried eating 1-2 types of fruits in one day, many types of fruits, fruits + vegetables + oats, 1 type of fruit and 2 types of vegetables.
I've learned that the less different kinds of food I eat the easier it is for my body. The less negative effects like bloating/gas. I also feel better if there's a longer period of not eating. Eating fruits and veggies all day long and not hitting 2000 calories seems like fun, but I don't feel like it's a healthy thing to do. Personally, I'll try to stick to less meals and more time between them.
Also because of feeling healthiest when eating only one kind of food in one day, I'm going to do alternating mono days. That way I can still get all the different nutrients from different foods, I just won't be eating the different foods on the same day! It's what I think works for me, it might not work for you.
I learned more about vitamin b12! "
The 2000 Tufts University study found
no correlation between eating meat and differences in B12 serum levels." Vitamin b12 deficiency can be caused by many things, and an insufficient dietary intake is a
minor reason. Most of the reasons have to do with preexisting conditions, disease or trauma to the colon. Vegans aren't automatically at a greater risk

The soy milk I use has vitamin b12 added to it. If you drink soy milk, look for b12 reinforced soy milk.
My anaemia symptoms have lessened considerably and I no longer look so pale

It's probably because of the iron in all the berries and fruits I've been eating
and the iron in the soy milk! (Soy beans are high in iron) Also I've been eating oatmeal and oatmeal has iron too.
I'm adding potatoes to my diet! Potatoes are rich in iron
I'm removing oats from my diet. I don't feel so great about eating grains!
I'm not sure what my body will think of all the starch. That's why I'm doing some potato only days to see how my body reacts to potatoes without being confused by any other vegetables/fruits. If potatoes work for me I'll be having some potato days between my vegetable and fruit days.
I'm going to keep the fruit days at fewer than my non-fruit days. I think there's a point to a high sugar diet encouraging inflammation or harmful bacteria and cravings. I'm not sure but it's possible. Starch is also broken down to sugar, another reason I'm not sure about the potatoes. And third reason is that I'm not sure if I want to eat too much cooked food and if I eat potatoes I cook (boil) them.
If potatoes don't work for me, I'll find something else
I know it takes time to adjust to any changes in a diet. More than just a few days. I'm experimenting to see how my body reacts to different things initially. I think if I listen to my body even before it's adjusted to a new thing it can tell me some things that help me plan my diet better.
