Green Smoothies....Questions

I used to make mine out of a couple bananas 6-7 strawberries and low fat organic milk and a scoop of protein powder for good luck but nowadays I just buy Bolthouse farms "Green goodness"...
I used them as a after workout refreshment or as part of a breakfast such as a smoothie with some toast...

I dont see why you cant make one and have it the next day...

Mine are at least half of my breakfast. Today I mixed a half a cup of vanilla yogurt, a quarter cup of 2% milk (it was too thick to mix right) a half a banana, 4 strawberries, and a handful of raw spinach. It was about 220 calories and it was my entire breakfast. I think if they aren't filling enough then you need to tweak it some. Mine end up pretty thick so maybe that's what is giving me the full feeling.

I am interested in incorporating them into my diet but just to clear up some confusion:

1/ Do they act as meal replacements? I hope not because don't think they would be filling enough for me. I was hoping for more of a snack.

2/ How long can they last? for example, can i make it the night before to drink for the following day?

3/ What are some of the easier recipes to make in a standard ordinary blender that's all natural and low on sugar?

Thanks very much in advance.

1. They can be pretty filling and big-my daily smoothies fills a full sized canning jar (what I actually use to drink them from ). Sometimes I use them as a meal and sometimes I use them as a snack, just depends on how my day goes/hunger is.

2. I've read that ideally you should drink them fresh, but I've read on a couple blogs/sites that people do make them the night before and put them in the fridge. I don't know how many nutrients are lost doing it this way though. It really only takes a couple minutes to make one though, especially if you prep your veggies and fruit ahead of time (have the greens cut up etc).

3. My basic recipe that I use several times a week (using a blender):
-2 cups water
-tbsp chia seeds (add these to the water in the blender and let sit a few minutes), or another seed-flax, hemp etc
-handful fresh spinach
-handful fresh kale
-1 banana
-1/2 cup frozen blueberries (I picked them this summer and froze about 20lbs of them for smoothies)
-another fruit-an apple with peel on, other berries, a peach etc etc. I just discovered that Dollar Tree has started carrying bags of frozen fruit so I'm using that now-mango, berries, peaches etc (only ingredient is the fruit)

I always blend it twice to make it smooth

Personally, not a meal replacement for me. My green smoothie's ring in at about 130 calories and that would just be ridiculous. I use them as a supplement to veggies, so I have greens and a green powder, so I don't want them high cal or high sugar. I use 1 scoop green vibrance powder, 1 cup spinach, 1 cup coconut water, 1/2 green apple and 1/2 juiced lemon. Quick, simple and low sugar.
