Hi Sarah
I had six lots of CDT starting in March 2012. Following this I have continued in complete remission. If I remember correctly my PP levels went steadily down from about treatment number three.
Main side effects for me were thinning hair, metal taste that made food less appetising (I developed a craving for Salt and Vinegar Monster Munches!) and I got shingle which I didn’t recognise at first.
I survived it reasonably well and didn’t have the Dex days that many people describe.
Do ask if you have any specific questions.
Best wishes to you both.
Mavis
