Reducing the Azathioprine

So my vet suggested reducing Aza to 1/4 tablet eod (every other day.) I started doing that on Tuesday and am a little uneasy about it, watching Janine for a relapse. Poor Janine- I'm always looking at her gums and examining her eyes and belly for bruising or bleeds. But she seems to feel fine. She looks good, has good energy, and isn't too bitchy.
