Hi Ni
i was in a similar situation as you regarding hydroxcarbramide.
my first two weeks showed little reaction.the main focus was on getting the WCC count down to acceptable levels before starting on Glivec My Hydroxea dosage was then increased and after a total of six weeks my blood level my WCC dropped to around 20, I was then started on Glivec and have been on this since may 15th 2009. In feb 2011 I reached the optimum perfomance of the drugs with my last BCR/ABL results coming in at 0.00 ph+ cells, it has taken 20 months to reach this stage. Your specialist team will be able to advise you as to what will happen and will co-ordinate the treatment accordingly.You need to trust the specialist and try not to worry about the CML.
Professor Clarke at liverpool is my specalist. He sums it up in a statement he made to me in January 2010 when he said you live your life let me worry about the CML
I hope this reassures you on your path of CML.remember try not to worry too much.
Take care and good luck.
Stuart
