I'm good with adding a whole food smoothie to a daily routine if that suits you.
But I doubt that you would do yourself any favors by going all extreme about it. As a matter of fact - if you are talking most of your daily calories from the smoothies, I'd worry about how that much raw vegetable matter will be tolerated while your digestion is outta whack.
I'd start with one per day for at least a few days before I went all in. As a matter of fact, I'd probably not commit to going all in at all. I'd probably try something more moderate like: 'I think I'll do some smoothies while meat and eggs sound disgusting to me'. You will probably start to crave real food again pretty quickly - don't lock yourself into a rigid plan right away.
As you are also eating coconut oil you might consider sautéing veggies or even fruit as a another way to get some easy to digest vegetable matter in you.
Just my two cents - you won't do yourself any harm other than uncomfortable digestion if you do as planned above.
Feel better and get off those meds as soon as you can tolerate doing so.
