Oooh, bananas and strawberries are usually heavenly together!
That said, your smoothie contains a crazy amount of fruit--most people boast about downing 10 bananas in a smoothie. So, try eating half that and maybe temper the smoothie with water? Or add some oranges for a tangy taste to offset the sweet? I don't know if oranges combine well with bananas and berries, but the flavor combo's delicious.
I've got through 2/3rds of it, just trying to up the ante on my calorific intake. I had 18 bananas in smoothie the other day and managed to get through it ok, though that time i was gulping it a bit and not letting my saliva in my mouth intermingle with it before swallowing as much as i'm doing today.
thtas a great combo...but you have made a MASSIVE smoothie! although i can get more in i find i like having a 1000 - 1400 cal smoothie.
...oranges go really well with bananas, but ive never tryed all three together.
