About gall stones

It seems a lot of people here juice their veggies. I wanted to ask
you for some tips on juicing and also if you could recommend any good
juicers.
I have lots of trouble eating veggies, especially greens, because I
get terrible stomach acid & reflux from them. I have to cook broccoli
and spinach to death in order to digest them - which kills all the
nutrients. I was thinking of juicing them (not sure if you can do
that with broccoli), but I heard that the fiber can get lost with
juicing. Did anyone ever try putting broccoli or other greens in the
blender, so that the fiber isn’t lost…maybe making a shake or soup
out of it? Any tips would be appreciated. Thanks!!
