Hi Tina
I don't remember having any problem with my appetite straight after CDT but I did have days during the dex. bits when I only had small portions. After the dex days I ate anything in sight!
Also, I had major appetite loss after my stem cell harvest and during and after my STC.
My taste buds definitely changed too. I preferred savoury things and even gave away my Christmas tin of Quality Street because I went off chocolate!! :-0
You'll soon get back to normal. Meanwhile literally eat what you fancy as and when you feel like it. 😀
