How's it going these days
@Alex_B ? My only concern about using meal rreplacement drinks is it doesn't feel like a grat longer term solution. It could be your team are keen to sort out your meds and usual eating regimes so that you are morre comfortable around decent food.
At one point in my life I needed a short while on a supplement (on top of normal eating), but I had to stop it abrruptly and it upset my tummy dreadfully and I ended up on all sorts of drips, do to my electrolytes had gone wonky.
