brand new VSG here!
Hey
I am a bit like you and cant handle the sweetness of the shakes - my dietician suggested I buy a protein powder with neutral flavour.
That way you can drink it without the sugary hit, add it to yoghurt, soup etc etc when you get to that stage.
I have 3 tins sitting at home waiting for me to have my sleeve next Monday
Happy Healing - sounds like you are doing really well :)
