Guess that answers my question. On HU went for blood work every week, then every 2 weeks now every week. Started in May it is Sept the 4th and I last saw the Doctor in May. So all I get is that my blood work is fine come back in a month. So the only questions I get answered are what I find from this web site. I had a episode of AFIB had not had it in 20 years on no meds for it except metoprolol so I saw that AFIB sometimes happens 30 days after starting HU it was almost exactly 30 days after I started the medicine.
Hope this helps someone.
