Hi Chirley,
Good that you don't have any nausea

!
You know low counts are really an adverse effect of Vidaza and does not indicate that you will have a positive effect of the drug but of cause we hope that the result will be OK.
Valproic acid often makes the patients very tired (called somnolence)

The combination of Vidaza and valproic acid has showed good results in treating several types of cancer. I can’t find a study on patients with low risk MDS.
Kind regards
